Have you tried the using the 256 trick? I know Brad was looking into doing something with transports, but I doubt he'll have had time before the patch.

i think this is it "

"Thankfully, it's easily fixed. In your galcivAIDefs.xml, find <WartimeFocusSectorRadius> and change it to 256. There's a comment noting that it should be multiplied by map size... but this doesn't appear to have been added yet as of 1.2 (or if it has been, it doesn't seem to work). And do not go over 256 - it makes the AI go funny. 256 leads to the AI suddenly becoming quite aggressive at invading, if it has transports."
