Went in one of those blue mystery portals on floor 1. It sent me to "level 0", in a 2 tile room with a AI bot. Killed the robot, but the room had no exit. Tried reloading and now I cant even see the room anymore.
I have same problem... Im on like my third level of the mystery portal.... first 2 worked fine but now I cant see anything and room does not appear to have an exit.
