As of the patch on Monday, the Overload bug is back. I got it twice Monday night. The bug places the animation and sound effect on you permanently if you run out of ultimate while using the heavy attack ulti in combat. A side "benefit" is a permanent slow applied. The slow can be removed if you throw the heavy overload ulti and immediately dodge roll. The animation and noise can only be removed by logging out of the game.
This bug return is adding salt to the wound of your making the Dragon's Blood potions no longer provide ulti when out of combat (because you couldn't figure out how to solve the combat bug). After spending a LOT of time and money to get a stock of those ingredients for the Minor Heroism buff, it only works while in combat now. So I am stuck in the slow until we can engage in combat again.
I did try to post this in the bug reports, but that option is grayed out (bugged)?
