So we have this mod in our modpack, and when you try to tame the foxes with the apple it instantly crashes the server.

Which version of Mystical World is this in? Could you please provide a copy of the crash report?

Yeah,
crash-2020-07-18_20.35.28-server (1).txt I believe this is the crash file for it from the server. We are running the most recent version of Valhelsia 2 version 2.2.5.

That was rather frustrating. It turns out that code got converted to client-only... I think I've fixed it, and made a new release.
