Haven't played Skyrim in a month or two. Saw a new mod (Thomas the Train, if you're curious - pretty hilarious), decided to install it and try playing again. Played like 15-20 min or so, everything normal, mod working fine, visited a few towns, went back to Markarth to my house. Once I left my house, though, I got a courier that started Hearthfire and then was approached by the Cultists starting Dragonborn. I went ahead and started working on the Dragonborn quest, I'm in Raven Rock now. I most definitely purchased the normal, no-DLC version of Skyrim last summer. Anybody know how this might have happened? Can't say I'm complaining, but it is weird.

(I also got Dawnguard for free back when Steam accidentally included it in a patch, if that's relevant.)
