So, I was in QM as azmodan. Had my (upgraded) demonic invasion ultimate doing their swarm thing against an enemy monstrosity. We were well ahead in a comp stomp, so i didn’t really care if I died. The monstrosity gets me low, then I get ambushed by tracer who lands her ult on me. I should be dead, but instead I seem to randomly execute a “trample” (which I didn’t take) and evade the damage somehow. It’s possible that the nearby whitemane healed me through the damage, but the random trample is definitely a bug.
(For my own reference, in case the replay is asked for, it happened at 22:45)
