Another minor bug I just encountered.
In the Poison Elixir quest for Roland if you go in the hidden room behind the bookshelf and interact with the table, you get a message in the upper left corner "Objective Updated: Distract Roland". However upon going to him there's no such option.
After that once you go to the Alchemist and ask about that Third Theorem, the message "Objective Updated: Distract Roland" appears once again and only then does the quest progress.
There should either be a step in the middle or the option to distract Roland should appear after the hidden room is checked.
(As a side note, I both gave bread to the poisoned guy and talked to the Alchemist in Trademond, idk if that has something to do with thisminor progression bug)
