I'd bet it was all the teleporter drops. There were many times I would teleport to a location, Poof! You've been disconnected.
Usually we get to test seasonals even if there is "nothing to test" this year they didn't let us test the anti-monitor event. and It is on test.
I really wanted an update on access to my money, I don't like being limited to 3k, I prefer free money than all the episodes released since I buy all the episodes of my interest
Since this was an unplanned maintenance, and we're not shut down this morning, I take it we will be shut down all morning tomorrow (Thursday) for monthly update / loading of Anti-versary Event. You guys could let us know about planned down times earlier than the evening before (just something I've been saying for six years now). Yes, the Upcoming Events thread is a hint about when down times will occur, but doesn't include shutdowns for regular monthly updates that don't load new content.
No game changes were made during this maintenance. The maintenance likely resolved some or much of the issue causing voice chat to act up like that.
