This thing is endless.

Do you have Vanilla Expanded Framework installed?

Yes

I found a solution: I had an old 1.3 VE framework. After downloading the latest version, the bug disappeared.

nice! glad that fixed it.

Also a fix I found was in Dev mode under one of the DD options to delete dragon fire. You can see the fire spots to delete if you have the minimap mod.

Have you checked if you are using the most up to date vanilla expanded framework?

Post an hugslib log in our discord or here so I can review if you are still having the issue

Dragon fire still won't go away, it says i'm currently on the most recent VE framework... is there a way to like triple check or manually install that?

It's buggy for me too, I'm using rimworld of magic loaded before, and VE framework is up to date 1.4
