How to tell if this mod is causing the issue
Look to the game log or crash report, this often tells you which mod is responsible for the bug/crash. If it doesn't, backup your world and try removing mods from your mod folder one by one until the bug/crash disappears to tell which one is responsible.

What to do before you submit an issue
Make sure you are using the latest version of this mod. Also, make sure you downloaded it from curseforge and not any other website.

What should the submitted issue include
Always attach a launcher log or a crash report if the game crashes. If the issue only happens with other mods active, include the list of mods.
