Harsk encountered Skinsaw Man in the Foxglove Manor. Alone. 1d4 was thrown normally (unlike in some other cases for me), I then proceeded to temporary closing locations. One of them was Farmhouse with Amiri and Sajan. Amiri tries to close the location, summons a random monster. It's the Attic Whisperer. Amiri checks Wisdom (fails), then Sajan checks Wisdom (succeeds), then suddenly Harsk is fighting Attic Whisperer, defeats him with his anti-undead crossbow and closes Foxglove Manor. Sajan then tries to close the Farmhouse, defeats something minor, and then everything proceeds as usual. See screenshot for this strange situation.
