[Client?] Losing game ends promos after getting free win

Losing the first game after getting promos with a free win ends your promotion series as a fail.

I was g3 and dropped to g5. In my first promo game back to g4 i got a free win, lost my next game and was out of promos. Made it to g3 promos, again got a free win and lost my first game, Again was out of my promos. currently back in g3 promos.

Only reason i know its a bug and not me losing is i have checked my match history both times following the loss and only had that one loss with a win before it. the win that got me to promos. I have no proof, no screen shots or recordings, but its happened to me 2/2 times with losing my first game after a free win was granted. if i lose my next game and drop promotions again, will update.

Its kind of annoying to get knocked out of promos when you shouldn't be. I'm not really put off by this, but some people might really hate something like this happening to them. Sorry if this has been reported before, i didn't see anything yet. but then again i didn't look too hard :/
