So, yesterday, I was playing on Chapel as the attacking team, and was shot down right next to the EV. An enemy came to finish me off, so I popped my Matrydom. However, a yellow (Gamemode) XP banner showed up saying “Damage” as if I had damaged the EV. What’s more is that when the defender’s disabled the EV, it gave me “overflow” damage XP, as would normally occur if I was damaging it on the defending team.
This also happened to me today playing on Bridge, and it did seem as if the EV’s health went down, though I haven’t tested it or anything. Hopefully this helps fix the issue.
