Overproofed ny deli rye

Here's my way Overproofed ny deli rye. I was making another loaf for a new Yorker friend.. she loves this recipe most.  It's very basic and uses king arthur deli rye flavor powder.  

Anyway,  during my second rise,  I was called away for a while and it proved 4 hours instead of the usual one hour. Lol. I baked it anyway,  interested to see how itd take it.  The crumb and overall loaf is fine. It flattened out the dome top- no big deal.
