I've had numerous occasions where the heal/hurt beam goes to some random point on the map instead of my target. Also had a situation where I couldn't hack my firebase even though I was right next to it. Happened on SteelPeel arena, on one of the high arch bridges next to the other team's base.
Another bug I found is that supports can hack through walls, which personally i think is quite unfair and should be fixed.
Another thing, twice now I've died during the moneyball blowing up sequence at the end from throwing my air strikes and being unable to move away due to said sequence. And they've counted to my deaths.
