Used this world file for a few weeks, suddenly there's a crash on startup
"[00:22:41] [Server thread/ERROR] [minecraft/MinecraftServer]: Encountered an unexpected exception
com.electronwill.nightconfig.core.io.ParsingException: Not enough data available"
Here's the full error in console: https://pastebin.com/0AEAVz17
Having looked into other threads about this, I've already tried deleting the config file to no success. Fresh save doesn't experience this problem.
Here's the debug log: https://pastebin.com/VXcMYpcJ
I'd really love to find an actual solution, but if the save is bricked I'd appreciate it if you guys could point out how I could prevent it from happening again on a backup.
