Company B Campaign - Can't Branch to Insurgents

[Juramentado]

Hi Folks,

I finally reloaded after getting a Windows 8 machine and I found an oddity in the USMC Company B Sulu Sea campaign. On my old machine I had always played the PRC campaign so I decided to save it at the Branching Mission and play both. But whenever I pick the V-hex selecting the Insurgent branch, the AI keeps penalizing me 4000+ points for Arty Overload. Yet I was able to pick the PRC branch no problem. Any thoughts on how to fix this?

Thanks!
