Hi there! I see you're having trouble with Gacha Club resetting your characters on your iPhone with iOS 18.5. That sounds like a hassle. Could you tell me a bit more about when this happens? For example, does it reset every time you close the app, after certain actions, or randomly while playing?

Meanwhile, here are some common fixes you can try to prevent character resets in Gacha Club on your iPhone:

1. Save Before Exiting: Before closing the app, make sure you save your characters properly. After customizing or creating a character, switch to a different character slot or scene to prompt the game to save your changes.

2. Use Export/Backup Feature: Gacha Club allows you to export your characters as codes or image files. Consider exporting your characters regularly so you can re-import them if the app resets.

3. Keep the App Updated: Check the App Store for any updates to Gacha Club, as fixes for save issues may be included in newer versions.

4. Avoid Force-Closing the App: Instead of swiping away the app from the app switcher, try exiting using the back button or home button so the game has time to save data correctly.

5. Check Storage Space: Ensure your iPhone has enough free space; limited storage can sometimes cause app data corruption.

If you've tried these steps already or if the problem persists, there might be a bug or data corruption affecting your save files. In that case, here is a slightly advanced tip some users found helpful:

- After making a character, switch to another character or scene before closing the app to force the save.

If you want, I can guide you through exporting your character codes to back them up right now as a safety measure. Would you like to do that?
