Only problem I'm having so far is that when I activate the trainer it starts spamming the activated noise (like you're holding down one of the keys to use one of the functions of the trainer). Though it's not activating any options. Also I can activate options just fine though. Weird.
After using the mega items option, I can't upgrade any weapons with mods or the game will crash. Also the unlimited sprint option doesn't seem to work for me. Not complaining, just trying to help! You guys are the Best!
