Arretium CTD

[Kralizec]

Besieging Arretium with my Casse Bren (who is awesome, btw), I'm attacked by a supporting Romani army.
Twice I have played the battle, winning both of them, but the game crashes when loading up the campaign map window.
The second time I made sure I annihilated every last man of the city garrison (the reinforcement army in the battle) to see if that solves things. Didn't help. To get around this CTD I just auto-calced with the auto win cheat.
This is around 208 BC btw, the Romani are only just churning out those Polybian units if that's relevant.

A leftover of the reinforcement bug, maybe?

Seems like it.
Was there any enemy family members (from any army) that got away?

[Kralizec]

The first time, yes. Second time, no...I think.

I'll do a couple of tests with the savegame I still have: eliminate all family members, and if that doesn't work, eliminate both entire armies.
