Playing as Rome, first playthrough. RIS is the only mod loaded. Been really enjoying the mod.

Turn 171. I'd already burned my way across N. Africa and the Carthage faction is reduced to a handful of settlements in Iberia and the Balearic Islands. But out of nowhere a 20 stack of silver upgrade sword/shield units with no generals appears next to one of my (formerly Carthage's) towns, Bulla specifically. A mix of of all their faction units from every tier, including Sacred Band units mounted and afoot. No event notification. None of the settlements were in revolt. Didn't see a fleet drop the army off. All the units are full health. Some of the cards are showing default peasant (They are actually cavalry and missile units of various types), which I haven't run into before. Did a trigger I bug somehow? Is this a scripted occurrence in response to pushing the Carthaginians out of Africa? What gives? I appreciate a challenge, I suppose. But this challenge is pushing the Total Realism aspect of the mod.

Thanks in advance.
