Talk:CM Supernova/@comment-72.69.164.180-20141222004058

I'm here to report a very strange thing;

When I was playing onslaught single-player, the necrosis came and I had the CM supernova positioned (red). I placed it and it had held back a swarm of zombies for 3 min. Then the necrosis came and the boss died in 14 seconds, and the spawns were killed in 7. Is it a bug?
