There's a couple of regular characters that do the same thing on certain jobs.
Can't remember his name but the aging stuntman disappears in the church on his 12hr job, the finder will take you to him but there's no thumb. However if you can collect income from a nearby building then the IRS will collect him for you.
Also the character from Itchy & Scratchy Land (can't remember his name either) has a job where he visits different buildings and his thumb icon disappears while he's inside as well.
If you can't catch them with the IRS then they will eventually reappear, it's just annoying that the finder won't move on to the next character until they're cleared.
