Hi! I understand you're having trouble with the GB calculator in the FoE Helper app where a temporary fix works but doesn't last after a reboot. I'd love to help you get this sorted out.

To start, could you tell me a bit more about the issue? For example:
- What exactly happens when you try to use the GB calculator after a reboot?
- What is the "temp fix" you've been using?
- Are you using the app on your Windows device or as a browser extension?
- Have you noticed any error messages or unusual behavior in the app?

This will help me guide you through the right steps. Meanwhile, here’s a general approach we can try to see if it fixes the persistence of the fix:

1. Clear Cache and Data for the App or Extension:
Sometimes cached data can cause the app to revert. Clearing it might help.
- For browser extension: Go to your browser's extensions page, find FoE Helper, remove it, then reinstall it fresh.
- For the app: Try reinstalling the app after uninstalling it, which will clear stored data.

2. Check for Updates:
Make sure you have the latest version of FoE Helper, as developers sometimes patch bugs related to GB calculator functions.

3. Re-add Your Account or Helper API Token:
If the calculator needs account syncing or a token, removing and re-adding it might restore full functionality.

4. Check for Conflicting Software or Settings:
Antivirus or browser privacy settings sometimes delete or block helper data, causing the fix to disappear after reboot. Temporarily disable or whitelist the app/extension.

5. Review Official Updates or Forum Posts:
There have been cases where server or database changes disrupted FoE Helper features. The developers may have posted temporary workarounds or ongoing fixes you can apply.

If you’ve already tried some of these or if you want, I can guide you through each step more specifically. Just let me know!

Are you comfortable trying these out, or do you want me to walk you through detailed steps?
