Sometimes I finish a quest or am in the middle of a quest and I try to interact with what I need whether an item or npc to continue or finish the quest but nothing happens so I'd have to leave the area, which is usually in a dungeon-like room, and redo the entire area and then I can proceed or finish the quest. I don't know how to reproduce this bug
