Thanks for the answer In my case that is not a big problem since I want to play with 2-3 friends and nobody from us wants to cheat, but knowing how to reset inventory is nice. Unfortunatelly new problem appeared: - changing ResetID=(some number) doesn't change anything - changing ServerPlayerID=(some number) will give the prompt "Player does not appear to have been created on this server" and freezes on the black screen forever PS:That's great the PZ has an option to play co-op! This is a reason why I actually wanted have it, I don't really like to play single player anymore and games market, even it's so big right now, is really weak on the side of co-op games
