This one's on Ken.
Typical Build shit. The function getzrange, used to detect the room a sprite has, has zero facilities to exclude the checked sprite from the set of data it clips against. For flat sprites with collision logic this means they will never have any room to exist in and get pushed up by one map unit each frame, because the code is dumb enough not to validate anything and just write over the data getting passed in. This is one of those moments where I ask myself how these games ever managed to get released without immediately falling apart...

EDuke32 fixes this, but in GDX it's the same as here.
