My game froze yesterday, and upon logging back in, I was stranded in Annuminas (where I had travelled to just before the crash). All my waypoints (custom and standard ones) have either dissapeared or locked. All my faction rep has dissapeared (the men following me have switched to acting like standard NPCs), and my quest log has reset to default (i.e. new game).
I'm running the 1.7.10 version of the mod on Forge 10.13.4.1558. I've tried following the standard minecraft guide here: https://minecraft.gamepedia.com/Tutorials/Recover_corrupted_saved_world_data
but with no success, as the copied world crashes to desktop when trying to load.
Can anyone help me? I've spent weeks buillding major settlements and structures in the game, and I'd hate to have lost them all forever.
