Summary	08227: lrescuem2: Collision detection is broken.
Description	Collision detection is broken for this game. During attract mode the players ship descends and lands on the far left pad like normal, but during the ascent back towards the mothership it doesn't collide with a ufo and continues upwards and out of the top of the screen, erasing the background graphics then wrapping around back through the bottom and does this forever. Playing the game results in a hit or miss with collisions, more times missing and going through the objects that normally kill the player. You can some times land on the ground pads but you can never return to the mothership, but instead go right through the top of the screen like during the attract mode. All other clones uneffected and play normal.
Steps To Reproduce	Load and run the game.
