Team Declines Penalty, Gives Up Touchdown

So this just happened in MFN-19: https://mfn19.myfootballnow.com/gamecenter/view/1836#351839

I mean I like getting defensive TDs, but I usually earn them.

From the game log:

2-17-BAL 6 (10:55) (77-Lemuel Arnold) 5-Michael McCullum FUMBLES (77-Lemuel Arnold) recovered by PIT-55-Franklyn Lynch for -5 yards. TOUCHDOWN! PENALTY - Facemask (PIT 74-Ralph Purdy) (Declined) BAL 0 PIT 6
