Commish dilemma advice-member claims ESPN app error

I am commissioner of my league and we had a strange thing happen yesterday and I'm curious what other commissioners would do.

Team X was in the semis this week, and their game came down to the Monday night games. Team X had the GB kicker, but did not put him in his lineup (or any kicker), costing Team X the game.

Team X owner later texts me saying he put the kicker in his lineup, but the ESPN app must not have taken the change, and he wants his kicker points added.

I said it was a tough break but I couldn't do that. I think Team X owner just forgot, because when I looked at our scoreboard on Sunday, I noticed he didn't have a kicker in, but the GB kicker was on his bench, so I figured he would put him in at some point.

Would any of you have allowed the kicker points to count after the fact?
