Haven't seen this before, but Donovan just visited me to request some Auras.
Unfortunately, I clicked through his text (as I usually do), so I didn't get a screenshot, but the second screen text was missing and instead had a tag that was something that started with: [donovan_visit...].
It just happened a few minutes ago in my shop.
