Champ Select on Blue Side - Game Loaded In and We Were Red Side

We went through all of champ select on Blue Side. I know we first picked, blind picked Yasuo, and they last picked Blitzcrank.

However, when the game loaded in we were Red Side. I wasn't paying attention to the loading screen so I don't know when the switch occurred.

But we were supposed to be Blue Side for the game but something happened and we were on Red.
