Aerie seems to have lost interest in me, just when I was getting interested in her. In ShadowKeeper, she is still 2 in AerieRomanceActive, and AerieRomance is 4503332. How can I re-kindle the love we once had? I don't want to go back into the arms of Jaheira!

well if your reputation is low that could be the probelm, also it might just take some time. I am not positive about it, but every time i have played. different parts of the romance are unlocked at different times in the game. sometimes you been to just stand still for a long while to get them to talk, others you need to camp for the night. My very unsagely advice would be to just give it some time.

I bet she is just playing hard to get. Just give her some time.

But if you don't want to wait, you can try this:

CLUAConsole:SetGlobal("AERIEROMANCE","GLOBAL","1")

But keep in mind that if the next lovetalk is event activated, it will not trigger it until the event.

As far as I know the Aerieromance global is sort of a timer, counting down to the next conversation. Setting it to one should start another dialogue really soon, but it may also be that there is a trigger, which will usually be resting.
Try waiting or manually decreasing the aerieromance global, and if that doesn't work, try resting, walking around at night, at day, in the forest etc.. Though it probably won't come to that.

Reputation has nothing to do with romance unless you get to the "break-point" for aerie that is at 1 or 0.
The romance in SoA is based on a real-timer,that is you get 1 dialogue after aproximately 45 minutes with Aerie.Some of the dialogues are rest triggered,that is you have to rest to happen.
Setting the Romance Active to 1 will not achieve anything.It is by default set to 1 when you begin the romance.
If you need more detailed help do tell me your LT rating and your Romance Variable.BTW I mean CLUAConsole not SK.
