I've encountered some more bugs, so general report here:
1. In the tomb fight with all the undead scribes, they're casting the spells, the animations are going off, but the spell itself never seems to appear. They cast Sleep and Firebolt, for example, but the spell never arrives at the target.
2. Cut scenes in camp with Halsin after Goblin leaders defeated. Halsin's mouth is moving, but some of the dialogue audio is dropping out.
3. Cut scene with Karlach - Her hand looks to be about 4-6 inches away from the stock of the crossbow she's holding. Telekinesis maybe?
4. Because of the roundabout way I've been navigating the Underdark, I landed in a fight with both Minotaurs AND the Bullette at the same time. :o The Bullette appeared above the party, then 'Dashed' and jumped down, knocking the party over - and then became stuck. The turn wouldn't end, and I couldn't do anything. Had to forcibly shut down the program and restart.
So just my two cents. Not sure if anyone else has encountered these issues.
