There is a chance that the air will turn into dirt after my server restarts

[PathdarX]

After my server restarts, there is a probability that all the air will turn into soil. I'm not sure if this mod is causing it,It may have caused the level.dat to be damaged, and when I replace the old level.dat, the dirt will turn back into air，Before restarting, the server will experience a series of chunk errors。
This is the erros before i restart

This is after restarting
