I have the latest version (2.517) of BGEE installed (Beamdog client) and I attempted to install the NPC project mod with the music pack. It seemed to have installed correctly (no error messages that I noticed) and I selected to add everything when prompted. However, I've started a new game not noticed any of the new dialogue banter. My current party members are Shar-teel, Dorn, Xzar, Montaron, & Edwin. Playing as a half-orc male but didn't get any of Shar-teel's romance dialogue despite having her in my party the longest.
Also, I took Xzar to the Cloudpeaks Dryad but his dialogue with the Dryad did not initiate. Perhaps I chose the wrong folder to install the mod into?
Edit: Apparently I previously attempted to install the 3rd edition mod but that didn't work either.
