1.20 has crashed a couple times on me the last two days. I do not remember the circumstances of the first one, but the second was when I was in the champion promotion screen. I selected a promotion and everything stopped and the cursor changed to the Windows cursor, then the game closed. I also just completed a game by casting Spell of Making and the bug with finishing research the same turn the spell casts is still there. This time I got to see the ranking screen, then the research window popped up and neither the Done or Cancel button did anything even though I was able to choose different research items within the window.
