Crash Log
https://paste.dimdev.org/ewecohezik.mccrash

Info (please complete the following information):

• Modpack Version: 2.76.2
• Server or Singleplayer: Singleplayer, but LAN
• Version the world was created on: 2.76.2

Additional context
A few minutes before the crash I moved a bed from doggy talents, but other than that I did get an error message when I killed a squirrel, but I hadn't done that since the start of the game a long time ago.

A little before the crash I used a splash potion of invisibility

I put a spruce dog bed down and it crashed again

So it's not a Primitive Mobs issue, but Prim Mobs dev is looking for a workaround on his side to not run code if Doggy Talents is installed. Waiting for either Doggy Talents dev to release a version with the null saveId workaround or for Prim Mobs to release their workaround.

I think a chameleon tried to walk on a doggy talents bed and didn't know what color to change to.

Opened Primitive Mobs git issue, waiting

DoggyTalents PR created percivalalb/DoggyTalents#244

Need mod update.
