Fixed carbine cavalry and imperial guard cavalry changing formation after dismounting and then remounting (it would become 2 ranks plus a third rank of 2 men, instead of just two ranks; it was very ugly, although of no consequence in truth). To anyone suffering a similar issue, it was fixed by changing the radius of their battle_entities to 1.5, and close formation spacing horizontal to 1.95; strangely, both had to be done to fix this, thus it was a great headache.
