So basically I just registered to ask about a problem I'm having. I'm new to the community, but I'm trying to test with custom tilesets. I imported a png image that I edited in Gimp. I then edited basically everything, the object, map 16, graphic, and tile behavior column in the tileset editor. I placed grass and then dirt underneath, and everything seemed fine. But, as soon as I tested it, all the tiles I placed had been replaced with random tiles from my tileset. Am I doing something wrong?

In the editor, when placing tiles, does it show the original tiles or the new ones? If the former, click the 2nd last icon at the top and click "refresh tilesets".

hey look, I did a thing

Also, don't put anything in the first rows of the map 16 to avoid randomization.
