Well, I finished the Candlekeep Catacombs, came out and Chapter 8 started. In Part 1 Fabio was in my party and left automatically before I transferred back to the Temple at Beregost. At Candlekeep, Fabio found the party, and used the scroll to transfer us to Restenford to meet with Pelltar. Then we went through all of the assassination and suspect dialogs with Fabio giving the correct interjections, and were given the quest to go to Garrotten and then Garrotten was revealed on the map just as it was supposed to be, so I travelled to Garrotten, and there I am now. So far everything works well.
Yep ... the same for me, no issue at all.
