Breaks...resuming

So after some yard work and family happenings, working eight hour days on programming. Interestingly I came upon a similar situation with building multiple levels in Game Maker Studio. Watching Shaun as he delved into multiple levels he has been pulling the map out for bigger floor formats but only a couple of rooms to do so. Makes for an interesting theory as I, again, created a new creature for the list of sprites. Moved the sprite in the list and the new object has a randomized sprite. No matter what movement in the list the object still has the same result.

So drawing a conclusion, I am wondering if massive room levels versus a few rooms pushes the sprite map out and causes it to get too full and overlaps the sprite map?

Hitting up the internet and yoyo forums for some insight.
