Fortnite v43.10: Buggy, Treasure Hours and Miku's Day
Epic's v43.10 Treasure Hunters notes in one place: Buggy's Captain's Day and what he drops, the first Treasure Hours (Cursed Sprites, two rounds on Saturday), Miku and Teto on Sunday the 15th, Boss weapons becoming guaranteed, Exotics in Chests, three new Sprites, the Locker grid and a new PC download option.

Fortnite v43.10 landed on Thursday, November 12. The short version: Buggy is now a Boss, every Boss is now guaranteed to drop his weapon, Saturday brings a new thing called Treasure Hours, and Hatsune Miku and Kasane Teto arrive on Sunday, November 15.
Everything here comes from Epic's v43.10 Fortnite Treasure Hunters Update Notes and the companion Fixes and Improvements in v43.10 post, both from Epic's Communities Team on Fortnite Communities. Times are Epic's. For the island, the launch weapons, the Battle Pass and Ranked rewards, see our Treasure Hunters launch guide; this post covers only what v43.10 adds or changes.
The v43.10 calendar
| Date | What happens, per Epic |
|---|---|
| Thursday, Nov 12 | Captain's Day: Buggy arrives at Buggy's Beachhead as the week's Boss. Cursed Kelper Sprite added |
| Saturday, Nov 14 | Treasure Hours: Cursed. Round one 2 PM ET (7 PM UTC), round two 9 PM ET (2 AM UTC Sunday) |
| Sunday, Nov 15 | Captain's Day: Miku and Teto at Friendship Villa. Leekcapper and Flapjack Rifle join the loot pool. Mini Miku, Squiplash and a secret rare Sprite arrive. A third Map Fragment surfaces that weekend |
| Sunday, Nov 22 | Oscar arrives with the Frenzy Auto Shotgun, per the Week 4 line in Epic's season launch notes |
A date check. If you have seen Miku and Teto's Captain's Day listed for Saturday the 14th, Epic's v43.10 notes put it on Sunday the 15th, and the Week 3 and Week 4 lines in Epic's season launch notes read November 15 and November 22. Saturday the 14th is Treasure Hours instead.
Buggy's Captain's Day

Buggy holds Buggy's Beachhead as this week's Boss. Beat him and Epic says you claim two things: the Special Buggy Ball and the Lever Action Shotgun. The Lever Action was on the launch notes' "later in the season" list, so Buggy is how it enters the pool.
That "claim" now means something. As of v43.10 Boss weapons are a guaranteed drop (more on that below), so a Buggy kill is a sure Lever Action plus his Buggy Ball, not a roll of the dice. Epic gives no damage numbers for either item in the notes.
Treasure Hours: Cursed Saturday

Treasure Hours is new in v43.10, and the first one is themed on Cursed Sprites. On Saturday, November 14, Cursed Sprites are boosted. The trade is the one Epic described for the Cursed Sprite in the season launch notes: carrying one raises your chance of finding rarer Sprite variants, but water damages you.
Two details from Epic's notes:
- Two rounds. Round one starts at 2 PM ET (7 PM UTC). Round two starts at 9 PM ET, which is 2 AM UTC on Sunday. Epic does not say how long each round lasts.
- Lil Uzi Vert's Lil' SMG drops in with you. Epic frames it as last week's Captain sharing his arsenal.
If you are going to farm variants, v43.10 also made the curse easier to read: Cursed Sprites now show a visual effect while the curse is active, so you can see when the water is hurting you.
Miku and Teto on Sunday

Hatsune Miku and Kasane Teto arrive at Friendship Villa on Sunday, November 15. Epic says that for this Captain's Day "the Captains come in peace", and the notes name no Boss fight for them, unlike Rocky and Buggy. What it does add:
- The Leekcapper and the Flapjack Rifle join the loot pool. The Flapjack Rifle was also on the launch notes' "later in the season" list.
- A third Map Fragment surfaces that weekend. The v43.10 notes do not say what the fragments add up to.
- Two new Sprites and a secret one, covered in the Sprites section below.
Epic also lists two known issues for the Kasane Teto Outfit: Back Blings may appear off-centre on it, and its colours may look paler than intended in Performance Mode.
Loot changes: Boss weapons and Exotics
Two loot changes from the Gameplay Updates section:
| Change | What Epic says |
|---|---|
| Boss weapons | Now a guaranteed drop. Epic's dev note: with several Bosses on the Island, it is comfortable having every Boss elimination drop one, so fighting a Boss is always worth the trip |
| Exotics in Chests | Some of the season's Exotic weapons may now appear in Chests, and "legend tells of one Chest that holds them all" |
Epic does not say which Exotics are in Chests or where the all-Exotics Chest is, and this post will not guess. The practical change is the Boss one: before v43.10 a Boss kill was not promised to drop his weapon, and now it is.
New Sprites
| Sprite | Arrives | Effect, per Epic |
|---|---|---|
| Cursed Kelper | November 12 | Increases the chance of rare Sprite variants |
| Mini Miku | November 15 | Grants a Friendship Bubble when you emote with other players |
| Squiplash | November 15 | Activates a healing smoke when your health is low |
| Secret rare Sprite | November 15 | Unnamed. Epic says it "may grant regenerating Zero Point Dash charges" |
Sprite fixes in the same update: the Chester Sprite no longer loses its fall damage immunity after you use a Vehicle, the Sweet Dreams Sprite no longer shows a placeholder icon and text in the inventory, and Epic fixed buying XP from a Sprite Dust Console sometimes not granting the XP. The launch Sprites and Mastery Monday are in the launch guide.
Quality of life and PC
Audio and map. If you run Visualize Sound Effects, the Chest indicator now shows an up or down arrow when the Chest is above or below you, and the indicator has a minimum opacity of 30%. If it is off, Epic's path is Settings > Audio > Sound. Our audio settings guide covers why it is worth having on. Undiscovered areas on the minimap also get more contrast, and the Battle Bus music has more variety.
Locker. A new Grid Density button next to the Search bar cycles tiles between Large, Medium and Small. The Up and Down arrows now move a full page at a time in the Locker and the Emote Wheel.
PC: High Quality Assets. The Epic Games Launcher now has a High Quality Assets option alongside the Epic Quality Assets option added in v42.30 on October 1. Ticking it downloads those assets to your PC so they are not streamed during matches. To find it, click the three dots on the Fortnite icon in your Library and pick Options.

Our performance and FPS guide explains the Epic Quality Assets download. The v43.10 notes give no download size for either option.
PC fixes. A memory leak when returning to the Lobby from islands, GPU crashes or hangs on DirectX, a potential Windows display crash, and skeletal meshes rendering at too high detail in Performance Mode with Mesh Quality on Low. Epic says that last fix should improve GPU performance.
Fixes worth knowing and known issues
Battle Royale and Zero Build
- Swapping weapons mid-reload no longer forces a fresh reload when you swap back.
- The Hammer Assault Rifle no longer shakes the camera after its mag is emptied.
- Digging up a Buried Chest no longer sometimes needs you to move or crouch to land the final hit.
- Controller movement no longer drifts diagonally on the Old School and Quick Builder presets.
- Toggle Inventory and Toggle Map keybinds now respond consistently and can be rebound.
- A railing at the Slurp Barrel Factory that blocked mantling is gone, and items in a warehouse at Plunder Port can now be picked up.
- Mobile: the Pick Up button stays available while you revive a teammate, and walking over Usopp's Galaxy Slingshot or the Lil' SMG with Auto Pick Up Weapons on now swaps out the lower-rarity version.
Other modes, from the Fixes and Improvements post:
| Mode | Fix |
|---|---|
| Reload | A memory issue that prevented 3 maps in rotation |
| Arenas | Duo pairing after a player disconnects |
| Fortnite OG | The OG Island could look more saturated than intended after a Battle Royale match in the same session |
| Save the World | A batch of fixes, including Piranhas and Cannonballs not damaging Husk Obelisks in The Grotto Dungeon |
| LEGO Fortnite | Spinjitzu no longer cancels on release, and the Storm King arena can be re-entered after an elimination there |
Known issues Epic is working on: some players can get stuck on a black "Relocating" screen after being eliminated and spectating, the two Kasane Teto Outfit issues above, inconsistent weapon damage in high-level Save the World Missions (particularly Mythic Storm King fights), and several Fortnite Festival Pro Parts and Main Stage issues (including D-pad input on the Main Stage Song Menu).
What v43.10 does not touch: the Fortnite Crew changes on December 5, which are in our Crew changes explainer.
