Help please!

Go to your map folder where your .map and .hps files are and you will see files that you didn't add. There will be .map_cache files that help load the custom story faster by compressing data. Delete it and you shall have no problems until you add something else. It would pop up again and not be visible ingame. Fixing it completely requires for you to set up a Dev Environment, as found on the wiki.
