when having a skill selected (for example bombers) the number available does not update when other selected ships with that skill come off cooldown
need to unselect and reselect to fire the skills that came off cooldown since selecting the skill
and there is nothing showing the cooldown of the other selected ships
so your just guessing when its off cooldown
and not using them simultaneously will just end up with pd shooting them down without doing anything

pretty sure in previous betas this worked correctly
somehow its broken now
