Wow! My clock for this post says you were up at 0305 hrs. Now that's early. I did put the dough in the same container, in the same spot. However, the time of day and the temperature was different. So, over-proofing is most likely the culprit. Thanks for your help. You're awesome!
I didn't know that you could control the humidity in the oven. Mmmm, do you mean like adding a pan of water or something like that? I am definitely going to purchase...
