UV footprints not showing

[Uncanny_Ally]

Don't know if it's an art/lighting issue, or coding, but UV footprints have stopped showing up for me. Neither T2 nor T3 UV light is showing UV footprints for me, even when I get fingerprints. And definitely not just Obake. I did a custom setup to ensure 100% UV, and standing over T3 salt with a T3 UV when it happens, and I don't get a single footprint. Been like this for about 10 days now (that I know of). Help is always appreciated.

If it helps, I am Prestige II - level 72, and I used to be able to see footprints so I know how they work quite well. Makes it VERY difficult to get UV evidence in some locations, and I've been jebaited by a couple of ghosts because I couldn't get UV no matter what.
