I'm a naughty girl and change all my variables with Shadowkeeper
I have found that Tsujatha and Anomen won't run together (my PC slept with both of them), even forcing them to run both on 1 with Shadowkeeper won't work.....the effects are very strange and mysterious.
Xan will run on 1 alongside Anomen without ill effects but will go into 2 even if Tsujatha is in 2. I can't remember if I tried both Xan and Anomen in 2 because of the conflicts I was getting with Tsujatha. I kinda customise my game, so my PC has run a little of Xans bon ded path and a little of the non bonded. The nasty surprises, I found, are shadowkeeper-able around.
Sorry if this sounds a little like cheating, but I play BG for the story and character interaction.....I find that by fiddling it a little, I can squeeze that bit more story line out.
I have the multi i-romance patch so Jahera, Airie and Viconia will run in 1 alongside Tsujatha and Xan - I find this quite convincing, as PC can form friendships with the female members of her party. I never let them get into 2 cos I'm not that way inclined
I'm getting ready now to do a mega install - there are a whole lot of new releases of older mods, such as TDD out. My next project is the Edwin romance and to see if I can stand Kelsey in 2!
