UV prints shouldn't be possible with Kupper as they are hard coded for the ghost which leaves them. Checked it code again for any mistakes but there not way to for it spawn a uv print. By the way, any text you find with torch is not considered a uv print. It should be a hand or breasts with hand to count as such.
As for Shy, it's breaking light bulbs as usual and didn't hunt for quite long. Shy and Weseen has same evidences. She doesn't break light bulbs and hunts early if break is off.
