Ship Combat Glitch/Freeze

In GAC today I used the Raddus to destroy an Executor I was fighting but then lost the fight shortly there after. I took my Leviathan in to mop up the remaining ships but discovered that if you use the sabotage engine ability when there isn't a enemy capital ship present, the game glitch/freezes and you have no recourse but to force close the game, automatically losing the fight in the process. 178-772-977 please review and fix bug. Thanks.
