also I have a softlock with steffa, when she walked in and accepted the quest and chose to poison the group of suitors, she didn't leave. I assumed she need a potion, but I had made the healing/protection potion, but failed in the third potion type. she then just stood at the door and I didn't receive anything nor did she leave when offered potions. I might have needed to give her a potion ingredient now that I think, but I had been distracted so needed to leave before I could test that. if I am just being a fool and am not understanding what she asked for you can tell me, but this could be an issue and takes a bit of time to get back to that point. I also couldn't get back into an interaction with her if I needed to, as it simply opened the door again if I tried to.
assuming the context that players are intended to brew potions when they are needed I understand where I could have gone wrong. my brain is in the make surplus mindset and that isn't what a brewing game is all about.
