Respecification not Slotting "unavailable" powers

[srmalloy]

It's got a trivial workaround, but when you complete a respecification, and return to the normal CoH screen with your power tray(s) that have all your power icons dumped into them willy-nilly, any power that is "unavailable" won't appear in the trays. This includes powers like Follow Through in Titan Weapons, which requires Momentum to be usable. It's still in your Powers window (and will appear in red, showing that it's unavailable), and can be dragged down to your power tray(s), but if you're not paying attention, you may not notice that you're missing one or more powers until some time later.
