When you're on a full server it lags really bad and becomes unplayable.
I thought it might just be me but my friends also get the lag and the connection error symbols at the same time. Two of us are in UK, another is in Germany.
I thought after the latest server wipe that with no bases or stashes that it would be fixed but within being online for an hour it's lagging.
Before 1.26 I played on De 3858 which was always the highest pop server and that lagged bad.
Now I've been playing on 1420 and it started lagging before night, eased off over night then soon as day hit and players started logging back on it started lagging again.
