What steps will reproduce the problem?

Literally just adding the plugin to my server creates this glitch (videos attached)

What is the expected output?

All blocks are removed, except for bedrock and gravel (because gravel falls). Console gives no messages regarding this

Towny version

Initially on towny-0.100.1.14, but updating to towny-0.100.4.0 still gives me this issue

Server version

I have also just tried to re-create this ticket. I started a server using 0.100.4.3, MC 1.21.1, claimed some land, unclaimed the land after a minute. No block corruption occurred.

If you have the time to diagnose this further or get it to a point that is re-creatable you're welcome to create a ticket or submit a PR for this issue which is apparently not occurring on all installations.

I checked and the issue began in 0.100.1.16 and was fixed in 0.100.1.21. Snapshots made in .16->.20 are corrupted.

Interesting. I reported the same on a "fixed version" 0.100.2.1 4+ months ago, without ever having used 0.100.1.16 - 0.100.1.21 either, #7411 . Still getting more and more void holes on 0.100.4.3 too.

This guy also reported it on 0.100.3.0 while only having used a 'broken version' for a day #7510
