Every time I use this mod it crashed when I open a world. I tried took all my other mods out and it still didn't work :(

Always show crash logs

This issue is being closed as a purge of issues due to the Morph rewrite to 1.12.2 finally being released. Support for the 1.7.10 version has long been dropped and focus has shifted to the 1.12.2 version of the mod instead.
