I have 2 bugs to report. not certain if anyone else has already posted about them but I didn't see them.
1. when doing the waitress minigame I got stuck doing it for like 30 minutes. no matter how much time passed I was stuck in the minigame with the clock just rolling over without going from 9:50 to 10:00 and instead reverting to 9:00 again. It was pretty frustrating as there's no way to end the minigame early without it running its course
I think what was happening is that as long as you are currently holding an order the minigame won't allow itself to end, as the way I got out of it was to just leave the character standing there for a full in game hour and then the time finally shifted to 10:00.
2. the empty vial is a usable item and I accidentally used the first one I recieved after receiving it from lucius for giving him the book. the next time I talked to him the dialogue had reverted to as if I hadn't even started the quest. I don't know if you could get another book for him because I just loaded my last save but I think it would be worth a look.
anyway I am loving the game, keep up the good work, I wouldn't be posting about these bugs if I didn't really like the product so far.
