So, whenever I make a new block in the blockset, the background bytes of all blocks that have a different behavior byte, (like: 61, 25, 02, 03, etc.) gets a background byte of 30 and behavior byte returns to 00. It's very annoying, since I constantly test the map. If I change all of the blocks back the way they were, they will stay that way until I add a new one.
Just a minor annoyance, nothing big. (I am using tileset 4 and 6, I changed them both).
