That's your image use in the current layout so you have too many images and animations loaded. Could also be particle effects but I've never really used them.
this happen cause i build a shop on layer...
cause i not know hot to buil on layout...
i have door in game.. when you go in collision set layer visible and inactive group of monster and player.. when i push n exit set layer invisible...
i think no is this way correct..
is simple do.. "go to layout" but when you do.. you "start layer" and i no want.. cause have other check.. "energy bar, gold, score, enemy killed" if i do go to layout all reset
