No, it was because a person who understands very well angles, focal distance and zoom posted accurate screenshots showing undeniable differences, and instead of acknowledging saying "we know it, but it's too much work to change the model and re-texture" they said "the model is perfect because we say so" and deleted any evidence.
That said, the MiG-19 here looks great, and a lot more polished than the Harrier, and I'm surprised they acknowledged this 3d bug report while they stuck their head in the sand regarding the inaccuracies of the Harrier, which are far more serious.
