I read your thread on rpgmakerweb. Since that thread is closed, you will not find validation here. You are in the wrong.
Buying a 24x24 tile set, clearly advertised as 24x24, and then whining that you can not use it in an app that uses 48x48. Oh wait, you do not even have that app, you need it for a different app, that uses 32x32. What a drama.
