So I was in FSC heating my arc razor and i was testing out the charge. I noticed that when you do the charge and do nothing after it, it's all good and fires. but then once you sheild cancel after the charge it doesnt fire AT ALL. It does no damage at all and you cant see it. I also tested it with slicing right after the charge then it also doesnt fire. I'm thinking that this is an old glitch but I don't know if anybody knows about it. It would be great if this was fixed but I don't think this will affect gameplay that much.
