Old School Runescape: Tinse Torpe and Sinco Doar are Invisible?

This is just a short post about a weird issue I had in Old School Runescape playing with the Runelite client. I couldn’t find any other posts about it anywhere, so hopefully this makes it to google well enough to save one person’s sanity. In the back of the Varrock museum, there’s an area for cleaning and identifying artifacts, part of gaining the necessary Kudos to take on The Dig Site quest. In order to turn in your finds, you must speak to one of two NPCs laboring away at a nearby artifact cleaning table, named Tinse Torpe and Sinco100
