I got into a play session a few days ago after staying in the queue for multiple days. Here was my experience:
I went through the tutorial area fine (tutorial tom had no legs, but that's a common bug).
I got the task to go to the trolley, so I did that.
Then, when I got back to the playground, I couldn't enter the doors to the HQ. The door texture was also glitching, leading me to believe it had somehow clipped inside of the darkness behind the door. So, I restarted, as I couldn't teleport to another world or leave the area until I went to the HQ.
Once I got back ingame, I was prompted once again to enter the HQ. Upon entering the HQ, I'd have connection issues and end up disconnecting. This happened the few times I tried afterwards, so I gave the game a break for an hour.
When I came back to the game, I was able to get to the toon selection screen, but once I selected a toon, I would have a connection error. It started doing that every time. At this point, I called it quits.
