There is a gltich that makes it impossible to go thought the door after fighting the spider tank. This is the door that makes Taniks appear for a few seconds, which allows you to damage Taniks a bit before he teleports again to another section. It teleports you back to the entrance of the spider tank figh room. Maybe is a gltich with the teleporter since it has the same animation.
Bump so Deej/Cozmo sees this. From what I can sya, DBMgamer had to return to orbit. Not sure if he had the same issue...
