Scans are broken in the main game. Ship scans, planet scans, full sector scans, single sector scans, you name it. I have also heard that spies are broken. I haven't gotten around to testing that for myself, but I heard it from the same person who was right about the scans, so they probably are.
Edit: working again
I figure you guys must have noticed it yourselves, but I just thought I'd post on here to be sure.
