Still I don't get you. You have played against a better team, CT against TIE, on the road, with very low offense stats...
Sure, you could have ended the three first quarters losing for 10 points less, or have scored 10 points more. Even in some simulations you could have had a close score in one of the three quarters, no one can deny it. We have seen it even against bots.
I really think your match is not impossible. Bad luck? Yes, all that could be wrong went wrong? Yes. Annoying? Yes, If it were a game of my team I would probably be swearing at home? Yes, too.
But, honestly, I don't thing your match can be considered bugged.
