[Hostlyy]

When i try to join my friends custom game in zombies it pops up with an error.

Hostlyy Is your friend changing the difficulty? If so do

gts zmDifficulty 0 

and then try joining.

He didnt change difficulty but it seems like I couldnt join him or he couldnt join me because i have project iconic mod menu on. Why is that?
