Not a Bug Double Uppercut Crashes Game

Description of the bug: (optional screenshot/video): Whenever I try to use double uppercut on my brawler the game crashes.
What is supposed to happen?: The skill double uppercut is supposed to execute
Where did you find and/or notice this bug?: Was training in Ludi, put a point into the skill only to have it not work.
A step-by-step guide to re-producing this bug (optional): Have other brawlers/buccs test it out?
Extra information (optional): At first I thought it was the rush bug so I restarted pc but it still didn't work. All the other skills I have work fine like corkscrew blow. (haven't put a point into backspin blow yet so dont know if it works) Ive also tried using the skill from the skill window, changing hot keys, changing channels, changing weapon, all that good stuff. Any help is appreciated. Also I have Poof's updated skill edit so that might be a reason for the crash.

 

Looks like it was the cosmetic edit. I probably should've tested that first. Thanks for the fast reply!
