Settled in for siege, rather than assault. Siege was successful and moved on to the next stage battle. After purchasing my troops the game went straight to the first turn; no deployment phase took place. I reloaded several times and experienced the same problem each time.
I then reloaded and decided to opt for the assault and had the same problem; after I purchased my troops the game went straight to 1st turn, I had no opportunity to deploy my existing or newly purchased troops.
I then used autodeploy and at least got everyone into some semblance of an order, only to discover I was not given any other generals other than the CiC; all my infantry were assigned to just one command; my lights were divided into a couple at least.
When I faced a relief force, it worked properly BTW
OK, ran into the same issue with the facing a possible flanking force; couldn't individually deploy units, had to use autodeploy get my purchases into some sort of useful position. No extra generals allotted.
Another bizarre thing, I had half a dozen troops become disordered when the enemy flank march appeared even though it clear on the other side of field from where I was deployed
