At first I thought it was just an artefact from appending the flow/domain and so I tried to make just a new domain, it's still there. I tried to make a whole new setup with the same settings it's still there.
I've included the picture of the problem. I have a pillar of smoke that works the same way the regular pillar of smoke but it's a second one that's showing up on the edge of my domain and I need it gone. I've already tried messing with my additional and margins and it doesn't help without extinguishing it all.
