This was pointed out a few days after the release of 3.0, and what you're stating is true, but with the sheer volume of problems with this game right now I'm not sure it's real high on the priority list.

Something happened. DC'd and can't log back in to any server.

I have this issue on two toons, a Trooper/Vanguard Armormech and Jedi Knight/Guardian Synthweaver. The specific schematics are everything that's been RE'd as others have stated. Also as others have stated both recently switched crafting skills. Figured I'd post this here as well even though I submitted tickets in game. Hard to believe they don't have anything up about switching crew skills until they resolve this.
