It was crashing so we did some comparisons. First, I collect what is essentially a frame by frame data "image" of 2 different moves that I know work fine.
I add the data to .txt documents from the point an input is selected until the time of completion. So I named one set ShadowBall.txt and the other Flamethrower.txt
I compared the pages to look for what each move did differently using a command called "git diff".
Then I did the same for the hacked move.
The game crashed. I created BlazingTorque.txt and compared the data. Found out that it was calling for an animation, and that adding the move manually was forcing it to do so (a poké gen tool likely wouldn't have done this).
Since it was calling for an animation that Skeledirge didn't have and there was no error correction for this, rather than defaulting to a generic animation or a glitched image, it just crashed.
