Another user reported the same problem, I'm checking it now (he sent a savegame to test). It used to work so I'm not sure what has changed!

Yes that's why I added that requirement, it was easy to miss it completely. Is in the neutral area on the right part of the screen, green arrow. It's where people are betting on the insects fights
My attempts at breaking Act III:
Ratmen show up in Act III even though I never met them before. The conversation clearly refers to meeting them back in Ninim, Act I, so no good.
Resting for the 25 days available in Act III before doing anything else, or just running out of time along the way, breaks the game (I told you I'd play the "not as intended"). You're no longer allowed to rest, and you can't do any romances. You can take one quest, but you can't progress after that, because the game requires you to rest before taking a new quest. I think it would be best to break the time limit up into smaller parts and force you to take the quests you absolutely must complete in Act III, like you do in the first 2 acts. Others may have better solutions. I don't actually know what quests are mandatory in the third act.
