I could list a few other bugs, but these two are the most important for the moment.

First bug is annoying, but can be worked around sort of. After entering the Valley of the Dead, the UI disappears after checking the inventory/character screen. Characters can move around, attack, the normal things but there is not way to click on the portraits, abilities, icons, etc. Changing area seems to return the UI, but again it disappears if I open the inventory/character window.

Second bug doesn't let me advance the game. Namely what happens is that I try entering my capital and the game straight up doesn't prompt me to choose if I want to appear in the throne room, inn and outside. The problem is that it automatically makes me appear at the exit of the capital and again the UI is hidden. Worse yet, I can't open any windows, click to move, talk or anything. It's as if a cutscene is supposed to trigger, but nothing happens. My character remains where he is, citizens roam about as usual, guards at their posts... I've waited for twenty minutes waiting for something to happen. Nothing. Since I can't enter the throne room, I can't check who's visiting (which is necessary to move on to the next chapter) and I can't progress with the kingdom since I'm constantly losing kingdom stats due to not acknowledging the visits.
