-mods needed in the screenshot

when it dies it make a ghost and come back with some health in its pokeball
if you disconect while its dying , it will permanently die on that spot
you can keep playing the same pokemon that died since it keep getting health on death
and create a ghost ever time
you can have 50 of them

steps to replicate
1 :cause the game to lag (i summon 700 / 1000 zombies)
2 : catch 1 to 3 pokemon from diferent groups that spawned AFTER the lag starter, whitin distance of the pile of zombie
3 : kill em, see if it return in the ball with health
sometimes it dosent but its rare, thats why i say to catch more than 1 from diferent groups
pokemon spawned by command and pokemon traded / recieved from professor arent affected by it

expected behavior (goes in ball on death and remain at 0 hp) and fully unload from the world on death

if no permanently dying entity if the player disconect while the pokemon dies
