When completing Bastilles for Taliesin's quest, especially the non-combat related ones, I'm often getting his poem popups but not getting credit for completing sections of his quest. I did a Bastille of Intellect, got the poem popup, but no credit. I just did two Bastilles of Agility, the first one gave the poem popup, but I only reached 1/3 quest completion upon finishing the second Bastille.
Same, I got all 5 poems in my codex but it says I need to do 2 bastille of might even though I did them already and got the pop up. It does affect the ability to progress because Taliesen won't let you do the riddle until you do the bastille of might.
Same issue here. I get the poem pop-ups, but no credit. Screenshot showing 2 poems in the codex, but no credit progression on the quest.
