Zoom out processing stalled

Greetings, it appears my zoom out processing has stalled. I am hoping there is a way to resolve without doing another full render.

You can see at https://map.rly.cc/?worldname=world&mapname=flat&zoom=0 that there are 3 missing tiles.

Zooming in will show that these chunks are all generated and rendered on other levels. This server is running Paper version git-Paper-"df1c8382" (MC: 1.13.1) (Implementing API version 1.13.1-R0.1-SNAPSHOT)

This issue still happens to my map, 1 year later.

Closing this issue even though it is older as there is a fix listed in the other and more issues are linked there
