Sorta freeze on non-player processing

[Midwinter]

I've his a weird bug and can't find a cure on previous forum requests.

I'm running 1.1 and all runs fine. I'm playing as the Greek Cities and have got to summer 235 BCE, but when I click the new turn button the game gets to the Lusotana faction and just stops. Not a freeze - I can still get the option menu up and the map is still animating, but the game won't move past the Lusotana.

So I went back a few saves and swiftly turn clicked into winter 234 BCE. No problem, so I went back and played properly... and got the halt at the Lusotana again.

The game is clearly processing something too big - I've left it to itself for a couple of hours and it doesn't move on. I'd just turn click past the propblem again, but that won't stop it randomly happening again.

Does anyone know a cure?

Thanks.
