Disconnecting does not appear to be resolved. I am getting massive spikes of server lag that last for a few minutes at a time and I have seen multiple people on my server (Begeren Colony) complaining about the same issue. I can't really do anything in game right now, because every few minutes I'll get another spike.
Exactly the same here on The Bastion. Started when I first logged on around 8am PT and it's still happening as of a few mins ago. Not a lot of ppl in chat seem to respond saying they've been affected but some have. These two issues obviously have to be related and they started after the patch.
I hope they revisit this issue because it's clearly still borked.
