I have a world that theoretically shouldn't have anything modded in it (has items in weapon racks mod), but it still can't be converted via drag and drop. At first i realised that i still had tmod supporter items in the world but that didn't solve the issue. I also tried opening the world and tedit and creating it as a new save in terraria/worlds but that didn't work either, just saying "loading failed\nno backup found" Is there any way to convert this into a terraria world at all?
