It seems that this mod and Better Archeology don't play well with each other. With both of these mods installed, the game crashes when I try to use an elytra.

Pushed an update to modrinth and curseforge that should fix the problem

Ah it seems that the CCLayer is missing an API call found within Curios API, I hope to fix this as Curios forks were merged back into the main so I am thinking about restarting from scratch to properly handle all the changes.
