Please, some words about this bug (resources / mobs.json)
sorry, i don't know where I can get information about it

 

If I run this pack on SteadFast, in 1.12 i saw the same, but 1.11 - client closing

 

But my friends server owners with mob's resources packs have the similar problem as https://forums.pmmp.io/threads/texture-pack-bugs-with-1-12.8274/

 

we tried to set up mob's packs to client except server, textures are correctly
