Hey guys, hopefully this is the right spot.
I followed the mod install guide on Reddit (https://www.reddit.com/r/kotor/wiki/kotormodbuildfull)
The Dantooine murderer quest seems to be bugged. I go through the first couple of phases of it, and get to the point where you're supposed to ask Rickard and Handon how they know Calder. The only problem; I can't ask Rickard that question. It's not an option.
So poking around, I found danm14ac.mod had been updated by the Community patch, among others. I started in reverse, of my install order, replacing the backup from each mod. Eventually, what got me through the quest was replacing danm14ac.mod from the backup folder from the K1.
I'm not looking for help, as I got by it. I just wanted to share this, in case there is an issue with scripts in that module. I realize, I've installed a handful that altered that zone, but like I said, only replacing the backup from this mod got me through it.
