Crash with Quark ?

[Blugori]

Hi, I got a crash when I showed uses for the lobster tail from alexs mobs.

Chat GPT says it's a bug with Quark and the foxhound.

Versions :
Minecraft 1.20.1
Forge 47.4.10
JEBr : 2.5.0
JEI : 15.20.0.129
Quark : 4.0-462

latest.log

For some reason debug.log wont load :
// This doesn't make any sense!

Hi, can you send me the modpack so that I can test myself?

After a bit of testing, it works fine when only these mods are installed. For some reason a crash occurs in the full modpack. When I will have the time I'll try to find wich mod is causing an incompatibility.

The mod pack is 450 mods+
