Hello! Thanks for bringing this to my attention! What version of Minecraft were you playing on? And was this for the forge version of the mod or fabric?

Nevermind, I managed to find why this issue was happening. I'll post an update with the fix soon!

Sorry didn't notice the reply. If it helps, it was on 1.19.4 and on Fabric
