I noticed this morning helping a friend get to dredgen I should check my seal. So all I had left was 1 invader defeated in thier super. I've accomplished this about 5 times today and it won't complete. First few times I was thinking my timing was off a lil... Maybe they came out of thier super as I was dealing damage... But I know for a fact the last titan i just killed was still in his super and I know for sure my rocket killed him. I saved video on my PS4 ... This is really frustrating. Wait and wait for super invader and hope I get the final blow before I die .. And to have it completed but no triumph is rediculous.
