Oh, I see what happened and where you're coming from. You were 1 play short of kicking the field goal as time elapsed.
I also can guess what the sim engine was up to. You were backed up by your end zone, the sim engine calculated it wasn't worth the risk of more plays and didn't fire off your time-outs. I believe where I picked it up there was a run or two. I think it was in hibernation/protection mode playing for the tie and not to lose the game via turnover.
