I tried my modpack with it installed, it crashed. I uninstalled it and it actually started up. Please correct me if I'm wrong and this is another mod somehow. https://pastebin.com/d8SpCCAc

Thanks for the issue report, at it's core this issue is being caused by an error in another mod, however my mod should not crash the game when it detects that error. I've released a new alpha which you can get here. Please let me know if this solved the crash.

If it does solve the crash, you should look in the logs again for error messages sent by my mod, they would look like this. Unable to load sounds.json for somemodnamehere. This will let you know which mods have broken sounds files.

Thanks, I'll check it out right now.

Ok, it runs perfectly fine now. I get all the way up until 2 other mods I have installed crashed, so I suppose I can check if it runs without the 2 mods.

Yep, it runs completely fine.

I am glad to hear it.
