The initial response from CS was a smug moron who cited my "poor bullpen management" because none of my short relievers were eligible to go in. I thought they were, but still, that doesn't really address the issue since I had other guys available. Whoever it was, he was a dick.
I then got a response from tzentmeyer saying that a) my mopup guy probably shouldn't have been pinch-hit for with a 6 run lead, and b) one of my 2 available Long A's should have been brought in when the first baserunner reached following the 3-run HR. He said he'll look at the logic.
