When in quest mode, encountering goblins (in my current case, I encountered Goblin Cutpurse) may cause the game to get stuck immediately after the dice roll. The modifier in question says "When encountering a goblin, roll 2d4 and add the total to the difficulty of the combat check". After the game rolls the 2d4, the encounter never advances to combat (or the wisdom roll in the case of goblin cutpurse).
Closing and reopening the game causes a new roll. Opening the vault and closing it causes a new dice roll. Returning to menu and going back to quest/continue causes a new dice roll. None of these options make the combat check begin.
