I've been playing this modpack for a week or so now and have had some minor crashes here and there nothing unexpected really. Though this last crash happened when i found a enderman wearing an enderbackpack, I went to sneak and right-click it open and my game crashed, not a huge deal really but when i restarted the FTB launcher and then the Horizons launcher, My world isn't showing on the Select Worlds list. I found the save files in the "AppData\Roaming\feedthebeast\Horizons\minecraft\saves" and the data is still there but nothing shows up in game.
Any ideas on how to fix this? Any help or ideas are much appreciated!
