Losing Promos due to bug.

So today, just about an hour ago, my friend and I decided to queue up for a ranked match ( I was in my promos for Silver I, and I had already won a match). We were in champion select and I was just about to choose my Champion when the client just crashed out of nowhere, I asked my friend if he was still in champion select and he said he was, and it was my turn to select a champ, although I wasn't there. Being the friend that he is, he dodged for me so I wouldn't lose a game in my promos, but when I had logged back on, I had lost a game in my promos, and he had lost his LP for dodging. I just wanted to post this on here in case anyone else had had a problem like this. Thanks for reading.
