Yeah, happening to me too in AQ against the mutant ultron drones. I used to get full charges after one fight because they’re mutant, now I don’t get any.
Those are robots. His kit says he can't gain charges from robots.
The error is in his description in the game as it is clearly stated in his spotlight that he doesn't gain any charges from robots
I think the problem is, at least last I checked, people have been making complaints about the champs and the focus isn't on the charges themselves. To be fair, I've been off the forum for about 2 months now due too work so... maybe I missed a thread that lumps all these issues together. If no such thread exists, I do hope more attention gets paid to what appears to be the core issue... Persistent Charges going inoperative at random. Any champ with them is susceptible to the bug.
