I have submitted two in-game bug reports, however I figured I'd post them here as well with more detail and add one to it.
Bug #1: The first bug happened when I hit ESC and try to log off, though it happens when I idle out also. Anyway, it doesn't take me back to the log in screen. My client just sits there with a black screen and background music playing.
Bug #2: The second bug is annoying, albeit hilarious. So I was making my way through the new black death lasers and some funny guy hit the gear thingy and made the walls blocking the lasers go down. Well I died, but on top of the "gear wall". Well when I was revived and the walls were put back up, I was stuck and couldn't move. Thus, I had to stay dead while the ran onto the lift.
Bug #3: Much like the level Crossing the Chasm to Haven, and The Core, the new Roarmulus level has a fog effect. Said fog effect absolutely destroys my FPS. The "low" quality setting should turn the fog effect off, it's annoying.
the fog effect should be optional
