I am running clean install and fresh run/save, latest version 0.4.21.
I found 2 cruicial bugs that break the game (cannot continue the game).
1) Cannot interact with master Dackin in the city.
2) If I start Gem quest: Dark castle from the city, I get teleported directly from city to final room with master in the castle (becomes evident later) and immediately start dialog. I passed Intimidate/Persusasion check, then he seems to give me the gem, and afterward everything seems to be broken (like playing quest in reverse). Finally I made my way out of the castle in reverse (with some fights, no Aksha etc just some minor skeletons, both floors), to the outer area with that pond/cottage and then I left the area. In the main city the quest is still marked as unfinished or not started even. Everything is now stalled.
Seems like that first and final teleport location are reversed?
