2 Bugs for ya:

First I found was if you have the soul jar for Gratiana, and you tell her you'll consider what she says and come back later (while she is at the staging point before they attack the harbor and I haven't talked to her before), when you talk to her again she gives you a message about liking you and no other conversation options.

Also, I already had the purging wand before finding Gareth, so when we got back to his seeker camp, I gave it to him before he walked back to camp. After trying to find him at the staging point, he was not there. I found him stuck on the platform at the original camp, and could not talk to him, though I could attack, and he responded to me having my weapon out.

Absolutely love the game, put 24 hours into a "12" hour adventure.
