Is this a new bug? Radiant quest sends me to Brahmin

I would have a screenshot but I was so surprised I honestly didn't think to take one. I have seen a lot of bugs in Skyrim but this is only my 2nd playthrough of FO4 so I don't know if this is a common bug or not. Preston gave me a radiant quest, deal with a kidnapping from Sanctuary. I get the quest marker, walk across town, and the marker is... over one of the heads of the local brahmin.

The left hand one. When I click, she wiggles her ears. But she won't tell me who was kidnapped.

... Which is probably good. No this isn't the one that was on top of a roof in my last play through.

Thoughts? I am playing with some mods including the Sim Settlement 2 collection.
