DOW 2 Angel's Gate Mission - No Option to Capture Gatehouse?

tttlllrrr

I can't progress because even after capturing everything else on the map and activating all the generators the option to capture the gatehouse is not available. Anyone know what to do or a way to skip the level so I can at least play the rest of the game? I am on OSX and can't get dev console to open, or would try that.
