Hey, i run Tekkit Legends on my server. One day it just stopped and now I get an error when I start up the server. It puts this error in the crash-reports folder: https://pastebin.com/mNn2j0C4 I did not install anything new or change anything on the server. When I delete the 'world' folder and let the server create a new one everything works fine. Is there anything I can do to keep playing on the current world?
