Hey there. Been trying to run your API on server, but got a crash. Would appreciate if you could help. Here's the code:

Also, just thought that a Bug label was probably wrong for this one...

Nope. Trying to rebuild my modpack rn, maybe that will solve it

Well, the problem magically solved itself once I rebuilt my modpack. So, sorry for bothering you, I guess.

That's kinda weird. Does it work if you load up only Curios?
