Jarl's BGT Adventure Pack: not compatible because you would have Svlast and Pilar twice
Comment: Not really an incompatibility. I have had NO problems. The fact that two exist does not really impact the game since this are not joinable NPCs. This component has some nice content that is really similar to UB and I consider it some additional unfinished business.
I would recommend install on this component.
For the last component that interferes with the Jaheria quest from BG1 NPC Project: I don't install that component. This is again similar to some UB content that interferes with BG1 NPC Content and just need to pick the one you like which is probably BG1 NPC.
I would not recommend install on this component
Of course this is my opinion and other people may freely disagree
I read Roxanne's comments in the other thread and took out Jarl's, but now reading her newer comments, I am wondering if I need to download a new Sandrah release and can use Jarl's. Clarification please. Since I am having run as administrator problems with windows 10, I have not yet been successful so I can still tweak my new game.
