Universal graves dissapearing after reopening the game

[PROTOthereal]

So i love to play minecraft with my GF but she often dies. I sometimes have to relaunch minecraft becouse the lag becomes unbearable from loading new chunks. after reloading the game, the grave dissapears. I dont know why its happening or if its a bug.

This happens to me too. I have a server with my friends and all of us have the latest version of the mod installed (Fabric loader). The mod is up-to-date on the server too.
Everytime the server gets restarted (manual restart or restart after a crash) every grave disappears and I have to go in creative mode to give everyone what was lost. It's really annoying.
If not for this problem this mod would be flawless!

The mod uses vanilla system for saving data, so that would only happen if you stop your server incorrectly while having auto-saving disabled. You can try also removing some mods that "try" to optimize saving, as they might be breaking things
