I've completed the game 3 times now with no major problems. The only bugs I have encountered are annoying but not game breaking in the least.

Minor annoyances I've encountered, without spoils:
1. A trader who is on my boat act 2-4 will not trade with me. His dialogue and trade screen show up, but clicking to buy or sell has no effect. Gear is hard to come by later in the game and he sells good stuff.
2. Quest logs in Act 2
3. Nonsensical dialogue

That is pretty much it. Other than those I listed, the game is solid and still the GOAT in my opinion.
