I have noticed a huge flaw in the after battle questionnaire.
I just had 3 battles.
2 were still running and 1 had ended.
I answered based on the match that I just left and then realised that it probably meant the match that had just ended whilst I was playing the last 1.
I think if it could at least mention the ship used in the battle at least you would be answering the question for the match that it was intended for.
