what were yo looking at - i'm about to do an update on the map will look for it - might be a metal grate texture gone bad
So going backwards from end point, right, up the track, left, left, thenthere is that longer multilevel straight. The offchute to the left (before the pit) I was running around trying to avoid a soldiers rockets. Ran into a wall or something over there and got stuck like that for the rest of the round. I switched classes, same issue. Disconnected and reconnected to server, didn't go away. I tried to delete the map and reload it, but i couldnt figure out which filename? Hope this helps
