Like everyone else, I haven't gotten this personal quest, either. I didn't even know it was a quest until I noticed the name of the quest on the Dragon Age wiki. I'm currently doing my second play-through as Lavellan romancing Solas, and I'm not sure if I should wait to see if this glitch gets resolved in a patch or not.
All I know is that it's sad that this quest appears to be...lying dormant.
god, if this personal quest has more romance content for solasmancers.. it needs to be fixed, because I always felt like there was something missing.
I WAS JUST THINKING THAT. While it made sense that Solas has a few less romance scenes than other companions story-wise, it...would also make sense if there's less scenes due to this mission not being triggered?
