I was playing on a multiplayer server, when I realized this, I closed the game, disconnected and killed myself, and nothing happens! even if I eat something

It looks like something de-activated your diet. Can you reproduce this in a single-player world? Otherwise, it seems like a mod or a server operator did this manually.

thanks, I took a look at the commands on your mod and ended up discovering the problem, I think that when we made some settings we must have been wrong
