Carthage Conquest Freeze

[MarcusAureliusAntoninus]

I've been playing a the romans a while and of course been at war with Carthage. I went around and killed all of their family members than when only the faction leader was left in Carthage, I gave them their territories back that I didn't want (I hate desert towns). All was well until I took Carthage: after the battle (I autocalc'd, I extremely outnumbered them), when I got to the occupy/enslave/exterminate option it froze when I selected one (any one).

At first I thought it was something to do with reinforcements (I had two armies near the town). I moved one away and tried again, it still froze.

I then thought that it may be a trait problem with Scipio Africanus or his son, leading the army, so I took them away and had just the army attack Carthage. It still froze.

I also tried attacking without the script activated or on a different date. Still no good.

After that I tried something different, I went in the character traits file found some traits that give bad personal security and gave them to the Carthage faction leader. I then assassinated him. It froze just before giving me the report that it was successful.

I now wonder if it has something to do with the desert settlements that never rebel. If they lose their owner do they not know what faction to become? I'll try taking all the desert holdings of Carthage and attacking her again...

Sorry to drone on... Has anyone else ever had a freeze like this when taking a city?

Edit: Oh yeah: I am using 0.7.4
