Just so every body knows.....it is OK rename the components and skin each component separately as long as you do not move/remove or add components.....or change the chassis in any way. I know that if you want to skin each flipper different you have to remove one.....or both, but they must be put back excatly like they were. DO NOT remove internal components, you will just have to reskin the original. I always made a new game for every skin contest back when we used to have lots of contests. You save the components folder ONLY if you need to delete the game for space reasons. (I have 1500 GB space, so I keep whatever I like)
