I am currently playing eternity death mode with my friend with a bunch of other calamity mod add ons. But my world has been corrupted or something, saying load failed no backup world. I looked up a video on youtube on how to back your world up and I tried it twice and I still isnt working. It might be because all these videos im watching are like 2 years old and these methods dont work anymore. If anyone could help me please do cause im so lost as of what to do now.
