Open it in worms map editor, set 18 holes, you can also clicking reseed for better hole positions, then save map. Upload that saved map. Information about holes is saved in PNG image from worms. When you open and save that PNG in other graphics editor, that information will be lost again.
Hey I'm trying to upload my first mole map. When I try to play it, it forces worm placement instead of generating some holes in the map for the worms automatically. How do I fix?
