So I'm not sure if anyone has been FREDding with the latest builds, but I've come across a MAJOR problem. All builds newer than Dec. 6th will crash when you try to open a mission, and if you look at the drop-down ship menu, it's completely empty. It still shows the default ship, and you can still place waypoints on the grid, but that's it. I haven't tried saving anything. Furthermore, debug builds will crash before you even get to the grid, with no message... even in Vanilla FS2.
[Edit]
Additional bug: Dec. 6th don't show object info when you drag the cursor over a ship. The box appears, but it's blank.
Here's my fred2_open.log file pertaining to the crash:
