Wow, this topic was active on 2016, but now it's stiil hapenning to me as well and I think I have the game up to date, 'cause I re-installed it a couple of days ago using the launcher from the downloads section.
At first I thought it had something to do with the auto-disconnect feature, but I also lost connection when I'm at the bank after shopping.
Is this problem still unsolved? Or do I need to change something?
It s*cks, really...
