Ok, this was kinda funny.
I was grinding up some Incedesaurs, in Searing Gourge, probably the 200-somthingth ive killed today.
I there was one withing my charging range, so naturally, I clicked the charge button.
At first, I didn't see myself move, I was like, why didn't it work, I look up, and the Incendesaur was charging me.
