Special rule: After encountering an undead monster, each character at the location summons and encounters Ancient Skeleton.
I encountered (from the location I was at), Ancient Skeleton, and defeated it, which normally allows me to close the location.
Because of the scenario rule, I had to first summon an Ancient Skeleton.
When the summoned Ancient Skeleton appeared, I used the Cape of Escape to evade and move.
Then, after moving, I got the dialog asking if I wanted to close my location.
I said yes, and it closed the location I had just moved to (all 10 cards, nobody had been there yet).
The original location remained open.
In case it matters:
Party: Lini, Valeros, Harsk, Ezren
Lini and Valeros were at the original location
Lini is the one who encountered the Ancient Skeleton and also had the Cape of Escape.
Lini moved to the Temple, which also costed a card (Temple location ability) when I used Cape of Escape (so that's working correctly).
There were actually 2 summoned Ancient Skeletons (because Valeros was also at the location). I resolved his first, and Lini's second/last.
