help with world being corrupt

basically i was going to make a world for a part of the server to have factions. However, once i decided to remove the world, it got corrupted, and told me to edit it or delete it. i decided to delete it still and removed it from the worlds list, but when i went to start it up again, i noticed that there was an error in the log even though it started. it still stated that the world 'Factions' was corrupt and that i needed to remove it for the server to act normal. Now i have to make sure to click delete every single time i want to start up my server. what do i do? i dont want to restart the entire server because i spent a long time working on it.
