BUG: Summoning half a wolf per forest province?

[Chazar]

Another turn came to pass with two werewolves summoning allies together within one and the same forest province. Both werewolves had a squad of wolves attached to them:

Each werewolf summoned up exactly three wolves. However, only three appeared within the province's garrison; the other three joined their brethren in the squad assigned to the first werewolf. This minor glitch is probably the sole cause of my misperception. It is odd that only one of the summoned groups appears in the garrison while the other summoned group joins an assigned squad right away...
