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 individual mods from your mod folder one by one until the bug/crash disappears to tell which mod 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 all mods you are using.
