[CLIENT] Tried gifting someone post-game and got an error

I don't know what the typical failures are for end-of-match gifting, so I can't really explain this. I would suggest simply friending them and sending them a gift after the required 24 hours have elapsed. You might consider asking the player if they are eligible for mystery gifts (if that's what you were giving) according to the Mystery Gifting Guide and adding that to your report.
