I've noticed a couple times when conquering an enemy city that I ended up with an extra champion there after I won. Maybe this is already in place
Damn! That would explain how on occasion, I too have found my SoV with more companions then I remembered. It does make some sense as well, considering you can go out and recruit, return to your City and exit, leaving them behind.
That does not bode well for the thought though that they, the recruits, should be helping protect your friggin towns...
Hmmm will need to TEST that. Has to be a BUG! I paid them to Die for me... muahahahahaha!
