I killed a haunted tool mob from the Primitive Mobs mod, and I instantly crashed.

Crash log: https://pastebin.com/raw/xmKvjpm3

From what I can tell, there’s a compatibility issue with the Morph mod. It might be because of the morph acquired effect upon killing a mob.

I reported this to @Vazkii, and he told me that it looks like this is an issue with Morph, not Primitive Mobs.

Self note: getEntityTexture is @nullable. Bear that in mind.

I also crashed upon trying to morph into a treasure slime from Primitive Mobs.

I’m not sure if this issue is related.

allso had this and with the firefly from twilight forest mods here the log https://gist.github.com/ashly138/f80af5d68ff51980ef226c5f020d29f0

@ashly138 that's a separate crash, same with #889. Make a new issue if you're not sure if the crashes are the same. I won't be able to fix this anytime soon though.

Made a new post. And gues till its fix i will just not go into twilight forest or restart every time haha

Fixed for next update.

Thanks!
