[MAC] CK2 hangs during gameplay "Preposterous datagram length"

[sampsen]

Recently started having an issue where CK2 will take minutes to load up the map on a saved game. Once I finally get that loaded and choose my character it will then randomly hang. I found this in the console log:

Aug 15 23:31:22 ck2[1839]: kCGErrorRangeCheck: CGSDispatchDatagramsFromStream : Preposterous datagram length -268435456
Aug 15 23:31:22 ck2[1839]: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
Aug 15 23:31:22 ck2[1839]: CGSResetPortStream: Resetting corrupt stream on connection 0x1015b.

I got a good laugh from that one, but I'd still like to keep playing the game! Any ideas?

Here are my system specs:

11" MBA Late 2010
1.6Ghz C2D
4GB RAM
Nvidia GeForce 320m

Is it only on this one save that has this problem? Under what game version was it started?

What version and checksum show on the main game menu?
