I just updated Puzzle Agent on my iPhone to 1.1. Since then, when I try to load a save game I created originally in 1.0 it just sends me to a black screen and just stays there indefinitely.
I on a 3GS running the stock 4.1 firmware. This is mostly just an FYI.
Edit: Yeah, just saw Telltale's note about this on Facebook. Nothing to see here.
