Not a fix, but they're gonna change the way building units works when buildings have multiple add-ons.
Most likely they'll merge the two different types and if you press 'D' it'll build a marauder on a techrax (when you have both techraxs and reactoraxs selected) and if you press 'A' it'll build a marine on a reactorax automatically. Rather than whatever you've tabbed to. (Which isn't generally all that obvious.)
