The modpack I'm using is a slightly modified version of the DW20 mod pack

Someone please help!

Mind sharing the fix you used? This has just happened to me after an automatic server restart.

The same thing with my server after a restart.

I'm not entirely sure what the problem was, though it doesn't appear it was in the world files. I reinstalled and copied my world from a backup and eventually got it working.
