Doing the quest riddles from the mushrooms to drop the barrier around the white witch. I answered one of the riddles incorrectly, but in my journal, it says not to worry and check with Zixzax. I go to my Homestead and talk to Zixzax, but not chat options regarding barrier/mushroom/riddles come up.
Quest is bugged? I have a save game that answers the riddles correctly so I can go back to that, but wondering if this was indeed a bug if Zix has no response regarding that quest.
