I'm new asf to creating maps but I really want to learn how to. I've been running into issue whenever I try to import bmp files into TileZed (I attached a screenshot of the error message I get whenever I try to drag and drop it into the program.) I've followed the tutorial (linked below) exactly as well as watching some tutorials on youtube. I have my vegetation map file and zombie spawn file as well. I have antialising disabled and overwrite enabled. I'm not sure what I'm doing wrong I've restarted a few times but I keep running into the same issue.
