So, I recently thought I'd dust off New Vegas and play through it again with fresh mods. Since it's been a while (and seeing as it's a Bethesda game), I thought the best course of action would be to just start afresh and reinstall the whole thing.
So far so good, right? Wrong!
After the game downloads, I see that I'm missing the DLCs Lonesome Road, Courier's Stash and Gun Runners' Arsenal. They're also gone without a trace from the Steam Account History. Since I've purchased this crap in friggin 2011, the only proof I still have that I ever owned them are the related achievements from here:

I filed a ticket with Steam, and eagerly await their answer.
Did anything similar ever happen to you guys? How did you solve it?
