I was just playing a friendly game on vassal and I kept losing my connection to the server. First a few times, then all the f**king time!

When I reconnected my user was logged into the game multiple times. Never seen anything like it.

My opponent was not affected.

Any tips? What to do if this happens again?

Exit and reenter is all I can suggest, if that doesn't work might need to reinstall vassal of it is a persistent issue

Never happened to me before. Restarting didnt help. Could be net stability issues on my end.

Very annoying. My Demolisher was just about to double-arc Screed acm and double-ram his weakened af flagship
