Dedicated Server Failed To Start

So aparently i decided to delete an old world before loading a new one, i clicked on it on the menu, deleted it and nothing new. Configured the new world and ooops, cant load the server, i had no idea why, but i couldnt. Aparently the game didnt delete the cluster folder 4, and the new world was trying to use that folder with new data to create the new server. I thought i had problems getting a cluster token, or something else, it turned out to be something stupid as the game not deleting the old world properly. Once i deleted the cluster folder 4 and created the new world, everything worked properly.
