The Americans on FX cut way short on 5/4

Did this happen to anyone else? The episode was a long one, something like 1 hour 12 minutes with commercials, and the Tivo (Premiere, ca. 2010) just treated it like a standard 1 hour episode. Good thing I was watching it near-live and didn't have things scheduled on both tuners at 11 PM, so I got to see the end.

My source is Comcast cable and I live in Portland OR btw, if it makes a difference.
