Upon using all of the mods (and only those mods) that are necessary to use this mod:

• Age-Of-Exile-1.16.3-1.7.7
• Library-Of-Exile-1.16.3-1.0.6
• Patchouli-1.16-36-FABRIC
• fabric-api-0.25.4+1.16
• curios-fabric-0.0.10-1.16.3

A strange thing happens where it loads the game, doesn't crash, but instead just loads then unloads then loads again on the Mojang loading screen of minecraft.

Closing all bug related issues as I just pushed a big update. (many changes to the code)
If the issue is still there, please create a new issue and provide new log files.

The 1.8 update is currently BETA which means it's not ready for stable worlds. If you are playing multiplayer I suggest you wait for a release candidate.
