I may have missed something or accidentally hit a wrong hotkey, but in prior versions, when done with an assault on the pirate home worlds, my fleet would automatically reform and sit at the edge of the grav well while the bombers would automatically begin targeting the ridiculous number of gauss cannons. 

After the patch, they no longer do so... the fleet still reforms and sits on the edge of the grav well, but in order to take out the gauss cannons, you have to micromanage the bombers, targeting each individual cannon  (even when they finish taking one out and are sitting right beside 3 more, they will just stop and not attack).

Am I missing something, or is this a common experience?  Thanks for your help.
