Meh, that was a bit anti-climatic for a 50th episode. 6 minutes long and no updates on the situation. With the weekend around the corner, it's going to be 3 days without any Persona action, maybe more if episode 50 can't be recovered by Monday and the guys don't want to move onto episode 51.
If it can't be recovered, just move on to the 51st episode. There were some good comedy moments during the camping trip but nothing important was skipped. Put a recap at the start of episode, covering everything that happened, and then continue. No huge issue.
It was funny when you guys talked about the possibility of a file being corrupted right before recording episode 50 and then faced the problem you had talked about. Hard to believe it wasn't fake but funny nonetheless. I'm going to assume it was real because, if the GB guys were looking for an excuse to quit P4, they wouldn't have made it so obvious.
