What i did / Steps to reproduce

I had a full bluemap rendered and decided it was time to "purge" chunks using external programs. I deleted a lot of chunks and then decided to run a couple /bluemap purge command for each map. All chunks that were deleted weren't (fully?) purged, only the ones that remained got purged and updated.

Expected result

I expected all old (no longer existing) chunks to be purged too.

Actual result

Only chunks that still exist got purged.

Context

Bluemap version:
BlueMap-3.5-fabric-1.19.jar
Using SQL storage
Map example: http://map.pandara.org/ (zooming in and out shows interesting results)

@Notoriousi Did you press this button:

No weird artifacts for me, on that map :)

Well, oops! I really thought I had, but after pressing it issue does indeed not prevail. Sorry for the issue report!
