FIX: delete the file with the name of the world you created and disable multiworld in FE. MW seems to have a cache for the world and eachtime it starts the server it will activate that cache and restore any missing data
I've been running a small server for me and my friend (and hopefully in the near future more friends) and it running the latest release of 1.8.9 forge server. The issue is recently I am unable to start the server because of coremods being present. Now I don't exactly know what that means. I've googled it and found that the problem may not even be with the mod mentioned, but rather with something conflicting with it. Anyways I was wondering if somebody more experienced than I could look at the crash report to tell me if its fixable or if I'm going to have to remove some mods. I think it will also help if I mention that the combination of mods used does work in sp.
Update: Seems to be a problem with the world, explaing why it works in sp. Once I've deleted the world I can run the server just fine. Is there any way I can recover the world though?
