  Issue Description

  I run a modpack server, whose mods are listed in the attached crash report below. Server crashes suddenly, but I checked 3 crash reports, and found that they are caused by similar issues related to GOG's horse.

These 3 crash reports below is generated by my server using GOG version 1.7.2, which is the latest version: https://paste.ubuntu.com/p/T7W6MTpBHx/ https://paste.ubuntu.com/p/qhTqCDF9Dz/ https://paste.ubuntu.com/p/mJTHXBnW35/

My server platform is Mohist. I have reported the same issue to Mohist's developers: https://github.com/Mohist-Community/Mohist/issues/235

Not much GrimoireOfGaia can do about it. It's the CraftBukkit implementation your using that's breaking
