Was just playing oddball on Haven with 2 friends and an enemy fused into the wall with the ball becoming invincible. He was clearly in the Wall and we confirmed it was him because he was gaining the time on the scoreboard.
The game is in my fileshare and the guy was:
x ID 3 3 J A Y
All three of us saved the game if you want more proof. Please patch this spot 343 otherwise oddball will on Haven will be ruined.
