I had a few minutes to kill and nobody was playing dp, so I filled Supermans Speed up with bots and changed to 3v3 tourney.
When the map loaded my name had changed to ACEBot_12, I coudln't see the scoreboard, my view was all zoomed in (fov still at 130). All kill notifications were gone too. It's like it applied all the bot settings to me..
First image is showing how my name changed to ACEBot_12, I am still logged in as OP, it says I have build 0, you can see how my view is zoomed in. And you can also see the messages about picking up items, which I always have disabled.
Second image showing my name is still set to Superman, but when I talk it shows as ACEBot_12
Third image just shows zoomed in view.
I will update my servers to the latest build some time today, just wanted to post this interesting bug.
