Server crashes because we uninstalled realsmoke mod

[VaruunKaruk]

Hey folks. Looking for some help on how to solve this issue.

The Realsmoke mod had issues whenever we had a smoke source underground, it would produce a smoke entity that incorrectly collided with real blocks, triggering so many errors that the server would actually shut down 
This is the Mod. https://mods.vintagestory.at/realsmoke 
We uninstalled the mod because we would have this happen enough that the server crashed.

After we uninstalled the mod, the server continues to crash, but for a different reason:

IS there any way to clear the smoke entities from chunks so this stops?

Thanks

Forgot to mention, this was the error when the mod was installed:

The only thing that comes to my mind is reinstalling the mod on the server and then making sure that nothing is burning--no kilns, torches, or anything else that could produce smoke. That way all the smoke has time to dissipate and you should hopefully be able to remove the mod without issue.

Otherwise, I'm not sure. You could also make sure that you have the latest version of the game and mod, since if you're running an older version you may be encountering an issue that a new version fixes.

I've seen cases where mod was added on worldgen, becomes part of code, so if/when its removed later it causes just this.

So Realsmoke has a command to despawn all smoke, you can also disable smoke generation. once i did that there were no more smoke entities. then was able to uninstall.
Thanks for the help everyone.

If you read the mod page, it lists the command you need to run before removing it so that all the entities are deleted.
