So the missile thing happens and constantly is killing enemies. Also when you respawn on the checkpoints your stats do not go to what they were before neither the stuff on the floor (like coins or gfuel resets).
In the meme cementery level I can bug one of the subbots in a wall, the one next to the secret coin at the start of the level. If I jump on top of it, it gets stuck in the wall. It is difficult to recreate tho.
