Level Editor Layer Inconsistencies
So I've been trying to create a few good Super Meat Boy levels on the Level Editor recently, and every single time I try one of two (or both) things happen: The buttons and tile placement are hard to use, but that's no biggie. The real problem is that when I start using more than one layer it screws up practically everything. Sawblades' hitboxes are wierd and can generally be walked through, Bandage Girl does nothing on touch; to win I must walk a few steps to the left to touch the hitbox. This is getting to be very frustrating since every single time it happens I basically have to start from scratch. Is there any way at all to fix this?
EDIT: For clarification, I have been putting a few sawblades and other props on the first BG layer as well as the active layer.
