I know why this It said Level -33. If you preform the Promotion Glitch where you glitch the “Imp Round-Up” quest, then do a glitch with chompers pizza missions, you can glitch your promotion and promote a character more times than you have earned. Its an easy way to get your characters to Master Rank, but the downfall is it messes up your rank and you still need to do the character upgrades by playing, and another effect is the negative levels visual glitch as seen in this video. Looks like someones been using glitches 🤨🧐
