"Desperate Nomads" visitor offer to join permanently even when quest ended

[onionleaf1]

"Desperate Nomads" Quest, --> visitor offer to join permanently even after the duration of stay is over.
There was not option to press Accept.
Details below.

Desperate Nomads Quest --> 5 desperate refugees joined temporary for 7 days till they regroup and leave.
I will name them pawn A, B, C, D, E.
On the 7th days, the quest completed, and all refugees starts leaving. 4 (pawn A, B, C, D) managed to leave the map, however there is one with a Alcohol addiction (pawn E) which is incapable of walking (due to withdrawal) did not leave the map.
He is downed and I rescued this alcohol addition pawn E.

On the 8th day, 1 of the previously leave pawn (pawn B) decided to join me permanently (i can choose "reject" or "postpone" or "view related quest") ( i cannot choose "accept" or "jump to location")

I believe this is due to the pawn B already not in the map, but the quest should end on 7th day somehow did not end due to pawn E still in my hospital.

Thanks for the bug report, the quest should end on the final day, not when they leave the map, I think.
