Alright, well my game was running smoothly I have PNG files for certain Backgrounds in the game.

When I updated to 4.5 I was able to use big icons ofcourse, but the background to the game gets totally destroyed for some reason (which I don't understand) and will also lag in certain areas.

I found out this code "world/map_format = TILED_ICON_MAP" and put it in the game and sure enough it works like a charm.
Although, the problem is, is that. The Backgrounds will work just fine but icons used with the new 4.5 icons that can be modified and exceed the previous limit of 32x32, get shrunken down to a mere 32x32.

Pretty much is what i'm asking is,
I want where my backgrounds work normal and at the same time my icons that exceed 32x32 be there original size.

Thanks.
