Crash Log: Link

In your environment, does the recipe book button work fine in the vanilla inventory GUI?

Yeah, it's only in the curios inventory that it crashes.

Hmm, what about in the crafting table GUI?

I can't reproduce this in my environment, everything works fine, so could you try to reproduce this without any other mods? At this juncture, this looks like a compatibility issue but I'm not sure which mod could be the cause and I'm not sure if this strictly needs a dedicated server to reproduce.

I had to rewrite the recipe book GUI implementation anyways, so I think that'll solve this issue. But do let me know if it doesn't and I'll re-open it.

Thanks! I'll be sure to do that!
