Repro steps:

1. Open app
2. Scroll back in the feed
3. After several days are reloaded, tap the picture of the day
4. Scroll to the previous day and tap picture of the day
5. Repeat

Expected results:
Picture of the day in the feed and picture of the day in the photo view are always the same

Actual results:
Picture of the day in the feed eventually becomes "one day off". The picture in the photo viewer is correct.
