Online play

So my opponent online chose to go for 2 points instead of a PAT. During the play i tackled his intended receiver behind the line of scrimmage forcing an incomplete pass but some how i got flagged for pass interference which to my knowledge isnt a flag. Anyway he obviously got a second chance to score 2 points. He successfully scored but the game awarded him 6 points AND he got to kick a PAT, turning a 2 point try into 7 points!?!?!?!?! Thats a problem thay needs to be fixed
