Just finished BG1 with Isra, and I enjoyed her very much. I'm looking forward to playing with her in BG2, perhaps as a lover for my <CHARNAME>.
One little bug. I installed the Valerie crossmod content, but Valerie wasn't in my party. Even so, Isra started up her first banter with her- 'I haven't visited Athkatla in... just under a year now. I would ask for tidings, though our social circles likely do not overlap at all.' That banter is checking for Isra being in the party, not Valerie, even though Isra starts the banter.
As Valerie wasn't there, the banter just immediately exited itself after that first line, but it's still a small bug, I fear.
