Hmm, you have been in game since season 2. Lets say you average about 25 games per season, which means you probably played about 450 matches already in this game. An event like this is probably very rare. I guess it's unlikely to happen twice in every 450 matches. Let's look at the bright side of the story. There's a good chance you won't experience this 'unrealistic' engine two times for the next 450 matches as well! (Although, be really careful in the scrimmage at the 10th of May, there could be a trend in this.)
Let's talk again in 2017
. It's a game of chances, statistics often feel unfair, must mostly (or always) aren't. You have won basically all that's possible to win in this game, I'm sure once you weren't at the wrong side of the metal all the time.
