I'm a good few hours in and wracked up at least fifteen approvals, but only just noticed that her slider never moved. I attempted to reset her by removing her from the party, then adding her back, saving and loading. I think that fixed it, as her Journal log then updated (albeit with only the Paladin stuff, no mention about her first Iron upgrade or other background).

However, I'm very nearly done with Act I and am afraid that I'd be locked out of the romance due to low approval. Is there any way to manually change this? Since I tried the remove-add back to party trick, I got all of the approvals from the Hag encounter, but her slider still doesn't move. Will going to the Underdark for more approval dialogue before completing the Grove (party) mess with the story at all? Any assistance is appreciated; I'm so far in now that the prospect of starting over would make me just shelve the game until a fix is available.
