Fire on water

[dangerousbrick]

I was fighting a Njerp camp, hiding behind a rock in the sea and shooting my crossbow. When I was done, I turned around and saw fire burning on water. Were they shooting flaming arrows or is this a bug?

Bug it is.
At first I suspect there might have been an NPC lighting a fire somewhere, but then the location had gotten corrupt for some reason.

Did you happen to have human companions around, or somewhere nearby?

[dangerousbrick]

No companions, just some animals on a nearby island. I'm playing with mods, but as far as I understand they shouldn't affect stuff such as making fire.

Thanks for the save. I'll check even though the issue mechanicsm is hard to find unless it keeps happening again during the test play.
