Yeah found the variables for that dialogue, this seems to be a hickup from imoen romance mod , she initiates a dialogue with you and triggers the first viable statetrigger which was the halrua portal thing rather than the imoen dialogue. The NEJ mod never changed those variables to a safe state and since imoen only initiates the dialogue once nothing happens after. Changing those two triggering variables made the dream sequence continue as normal.
That portal activation thingie is from the gallery in halruaa order to get out of there the variables need to be as is when your in halruaa but should be changed when you leave.
You get quite profficient at going through all these tons of data from correcting bugs;) thanks for your help
