I have several dozen hours in the game while playing online private and haven't had any issues.
Only way to Fully play Offline is to use offline mode for steam, or disable your internet adapter
Otherwise, choosing Private and selecting 1 player when going on quests is the only way.
Just don't use the cheats with other people and you'll be fine.
yes our easy kill is like no other trainer.. you absolutely wreck everything in the area..
Okie dokey, was just checking. This is what I ended up doing anyways. Thank you.
