Bug Description

After messing around in-game for a hour or so game completely freezes, using up all my CPU, killing and restarting the game reverts the saved world a few minutes back before it froze(i was playing in creative with structurize, placing roads, a few last placed roads were removed like they never were placed), never tried to wait longer till it crashes or unfreezes since my laptop will actually just fry

Reproduction Steps

just played around with chunky pregenerated world with a pretty big modpack and DH

Log File

latest.log .

I think you might just need to allocate more memory to the game; that crash looks as though it was busy trying to free memory, rather than making progress on generating the structure. DH is pretty RAM-intensive.

Removing https://www.curseforge.com/minecraft/mc-mods/fast-async-world-save-forge-fabric fixed the issue completely, dont know how...
