Glitches and hacks...

iAspire

I'm seriously mad off right now. Almost every Mutation Mode room is not glitch-free. I spend my entire game trying to block people from doing glitches so I don't end up being chased by all mutants while he takes the cake. Also hackers are not afraid to do it shamelessly in Public like they own the game. an urgent call to developers and CF staff... FIX IT... SERIOUSLY!!

Submit a bug report in a ticket (Not sure if you can include replays in here but if you can so it shows the process that would be best), and submit a hacker ticket (Glitch/non-hack) for these people with replays until it gets sorted. There is literally nothing else that can be done.

who will be there to fix bugs and deal with hackers, it is a small place. You send them a report and photo and video them deeply anyway. They only play in rooms with each other can, and not to deal with such hackers.
