Here's a thread full of bugs and negative issues I've been peeking in on. The title is a little tongue in cheek. There's a lot of serious problems with this game… or do you folks disagree?

That list is mostly wrong. It also sound like someone who haven't played the game for very long.
1. The fastest way to manage the Kingdom is to be on the world map travelling and click the kingdom button at the bottom right corner (no need to be in the capital outside of dealing with throne room meetings, talking to companions and selling stuff). You get 1 loading screen that way.
2. In chapter 1, Oleg's inventory added +1 weapons of various types over time and then I went there at the start of chapter 2 and there was new stuff in his inventory again. So merchant inventory do change overtime. Artisans allow you to craft stuff as well, including repairing artifacts you find pieces of during your adventuring.
3. Can't comment, I haven't tried auto-Kingdom management, but if I turn it on it is because I don't care what is happening with it…
4. I haven't got a single crash in ~30 hours of playing.
5. The game is totally playable without save cumming.
6. Monsters with the setting "enemy stats" set to normal and "enemy difficulty" set to weak have their normal Pathfinder stats (that's slightly higher than the Normal difficulty in the game I think, but lower than Challenging). This have been validated by someone who looked at the code.
7. I've yet to see something totally broken there, although considering the amount of features, some being broken is probably to be expected.
8. ---
9. There is a console, nobody knows any console commands for it yet. If you want to cheat, there is plenty of trainers already.
