I recently noticed that the new Mek update breaks AE2's recipes, all of them except for the quartz weapons.

I even built a new version to check to see if the bug was fixed recently, it does not seem that it is.

Also posted on the AE2 tracker: AppliedEnergistics/Applied-Energistics-2#1072

Closing this. Issue is on AE2's side, and they are aware.
