corruption Tekkit world corruption?

[_hunter]

Hello Tekkit Community, I am here to try and get some support on why my Tekkit world has been corrupted.

Every time I try and load the world, the launcher just crashes. Ive spent 12+ hours in the last 2 days on this world and I would really love to have it back. I do not have any backups of the world but If I can get this back I probably will do backups every 2 hours since this world is very special to me, lol. Anyways, thanks for any help I really appreciate it!
