However i've read on a wiki ->
"Sending out Pokémon, battling, or quitting/disconnecting whilst in the Nether may cause a corruption of data."
Now i can disable people from being able to send out pokemon, so they wont be able to battle, however i cant prevent them quitting/discconnecting.
I've also noticed that the data files containing pokemon are world specific, so if i log out and back in in the nether, i'll have a different set of pokemon than in the overworld. can this be prevented/worked around?
Thanks for the help anyone that responds. <3
