Q8: Why do I still have bugs after unsubscribing from a Mod?
Simply unsubscribing from a Mod is not enough—you also need to delete its local files.
Step 1: Unsubscribe from the Mod in Steam
- Open Steam → Library → Boba Cafe Simulator.
- Click Workshop on the right.
- Open Subscribed Items.
- Find the Mod you want to remove and click Unsubscribe.
- Steam may not immediately remove the downloaded Mod files from your computer.
Step 2: Exit the game and Steam

\Steam\steamapps\common\BobaCafeSimulator\BobaCafeSimulator\Content\Paks
and delete the corresponding Mod folder. - If you're not sure which folder belongs to which Mod:
Delete them all (recommended).
Steam will automatically redownload the Mods you're still subscribed to.

Completely exit the game, then open:
Steam\steamapps\workshop\content\3683770\3773644355

Step 4: Restart Steam
- Launch Steam again.

Q9: Why is my Demo save file gone?
To prevent Demo cloud saves from overwriting Full Version cloud saves, we have disabled cloud saving for the Demo.
Currently:
- The Demo only supports local saves.
- If you switch to another computer, your Demo save will not sync automatically. You'll need to manually transfer your old save files.
- To carry your Demo progress into the Full Version, your device must still contain the Demo's local save files. Otherwise, you'll start a brand-new game.
Q10: I transferred my save file, but I can't find it in the game.
- Do not change the file extension or file attributes, otherwise the save may not be recognized.
- We recommend compressing the save file before sending it to another device.
- If a save file with the same name already exists, replace the existing file.
- To avoid overwriting your current saves, we recommend manually renaming or placing the transferred save into an empty save slot.
Q11: The game shows the following loading screen for a long time.
The game is still loading.
This may happen if your device has limited available memory, which can significantly increase loading times.
Q12: How do I get Dried Fish?
Purchase a Drying Rack from the Farm App.
Place fish on the drying rack and wait until the next in-game day.
The fish will become Dried Fish, which can be used to trade with NPCs for various resources.
Q13: How do books refresh in Yan Ruyu's Bookstore?
Books refresh randomly.
Simply refresh the shop a few more times.

- The logos on delivery bags and the cup sealing machine cannot be customized.
- Cup logos and sealing film logos can be freely customized.
Q15: My items disappeared. How can I get them back?
