Hi, by looking around the web i didn't found anything helpfull or working for my problem, ill explain it in details here
Ive got a moded minecraft, but this problem is also affecting vanilla mobs, like Zombies
Some mobs, with i don't know with what kind of dark magic, have got their HP reduced to 0, but they are still alive ! Waila HUD says: That mob have got NaN/58 hp:
the current problematic unit is: A "Tamed" Pyro from RafradekTf2Weapons mod
-I cannot interact with it anym
