Only when i play as an Assassin the juice bar seems to bug out alot. Whenever i use juice, the bar will always remain full after that (no i dont get unlimited juiced, its just a visual bug) It doesnt seem to happen on any other class i play.
I've experienced this before. Not sure of the class i was but it was likely assassin too. It's an inconvenient bug when ur runnig headlong into the enemy base expecting to pulverise everything only to flap ur fingers about in a desperate attempt to not getting smear accross he opposing teams floor
