Why is there suddenly so much air in my umai bag?

Thanks RRP! Here is the end result after I put it in a new bag and resealed it 🙂 How does it look?

Seriously, Ron, you are the greatest! I was so stressed today lol. Just for my own sake, if this happens again on say day 20, would the steak be ruined? What would it take for it to be totally ruined?
