Custom Battle (BUG)

So i decided to play some Napoleonic wars today and when i went into custom battle i put in all the troops and when i spawned in the Ai Spawned Beside each other. No matter what i do i cant change it. They all spawn together and kill each other!

We've all been there. It's nothing you're doing wrong. The devs simply didn't code that part completely. It's a damn shame.
