Looking at the stack trace sounds like issue with MCL hunger, it should check if player is actually online and is real player.

Yep, there's only a useless is_player() check: (which returns true for fake players too) https://git.minetest.land/MineClone2/MineClone2/src/branch/master/mods/PLAYER/mcl_hunger/hunger.lua#L5-L7
