I didnt hack or anything, i was playing normally solo and then i went to the mystery box on die rise. i killed some zombies with the hammr

i went on to the minion round and placed my trample steam in front of me in the corner, since i was camping in that round.... i then jumped on my trample steam becuase there was a minion beside me and then as soon as i landed on it, i got into one of the walls and couldn't get out

so i was in a mistaken-wall breach... ended up going round 84 with 1300 kills 8 downs.
edit: i also ranked up 2 times in that game.
