I had a 16 vs 16 fight, and that's where I figured out the collision issue/crashed the game a few times. Without sufficient spread of the AI clones, some bad things can happen. At the very best, I had single digit framerates, errant killed by SERVER messages, taking hits without an enemy anywhere near me, and half the clones killshot each other. At the very best, I had all of the above, except only 4 clones killshot each other, and the rest scattered as the AI flight (half of whom also killshot each other) closed in, after which everything worked well.
