Issues I've seen so far that do not seem to have a solution:
1. After the scene with Roseus (post-defeat), there is a black screen. (Also noteworthy: it is possible that the update has reset your status with Roseus, as when I went back to her to see the scene I had to fight her again first.) This isn't a freeze-up, because you can get to the interface by hitting Esc, and your character isn't stuck, as you can see if you check your steps counter. If should be solvable by just retracing your steps, as mentioned above. However, the scene also does not show up in your log.
2. You can actually get into the Illusian Forest; there are three squares between the guards at the west edge of the first map, and if you walk through the middle one the guards won't stop you. However, the forest is empty of enemies and anything to do, though if you go far enough to either the northwest or southwest you will end up at some interesting places that will probably have to do with the story and/or have secrets.
3. There are only two new renovations on the castle that can be done at the moment. The first happens automatically when you show up past a certain point in the story, turning Warrengard from a ruin into a proper castle, with extra rooms and furnishings; your party is now in different places than before. The second opens up the door at the end of the central tunnel under the throne room, allowing you into the back yard. However, there is no indication for what this might be used for or even if it's supposed to be like that, and no workers show up for further renovations, even though Gabe's notes imply there are multiple non-story renos.
4. There appears to be no way to get Bal'Rana to do her strip dice game. (However, during the second prison breakout, I did not extract a promise of sex for helping her escape, so I haven't gotten a scene with her beyond her doing the Tavern Wench challenge in Odidania. This may be required?) I have also been unable to get Bal'Rana to do the Tavern Wench challenge more than once.
5. Sleeping to change the time of day when in the castle causes the game to crash due to it being unable to find "Graphics/Fogs/306-RuinedCastle009-Day" (or RuinedCastle009-Night, whichever you're switching to). However, exiting the castle, sleeping to change the time of day, and then going back into the castle does not cause a crash.
