For some reason, during my Cleric of Selune playthrough, the cauldron of boiling theriac is not usable. The entry is in the journal for what to do, but you can't interact with the cauldron. Anyone else had this issue?
Yes, me too. It occurred with the last patch or hotfixes. I also noticed that Larian replaced the original botany book Flora of the Dalelands with the advice (from EA) to use the cauldron for an "Elixier of Silvanus" with a new book about poisons in general. So I guess from now on we'll just have to make our own usual "Antidote".... Burdensome, because Larian's communication to changes is always a guesswork!
