V1.3.0.0
So, I had a pirate invasion happening and I was busy, so I left it be briefly. The rogue Korzan's then showed up on top of them.
By the time I got back and cleared up my doorstep, the Korzan quest either didn't finish or it did finish and didn't clear out of my quest log. Not sure which 'cause I didn't think to take note of it, and I just blew right past it.
I wish I had kept track of the data better, but that's all I've got.
