Unmodded installation from Steam. After the update, spacecraft that I was able to launch yesterday contain "locked or experimental parts". I can see the parts in their normal places in the R&D tree (see screenshot). However, the AE-FF1, one of the nose cones, and one of the solar panels are missing in the toolkit when I go to build or modify a rocket. This is really disappointing, as it blocks me in my contracts! I have already verified the integrity of the game cache with Steam, and it shows no problems.
