I never thought it would be possible, but the map has gone from just vaguely workable, if annoying, to a total and utter mess. An exercise in frustration and how not to do things. Pop up menu that blocks selecting other systems and difficulty actually getting the selection tool arrow to actually register a selection.
Some strange drops in graphical quality that were not there before, and some CTDs. Frequency a little less than before.
Also had one complete dump out from the map that somehow restarted my PC.
Trade data/routes still not making entire sense. I'd say that's a fairly big issue.
Otherwise , ok but FD have a lot of work to do if this is not going to get it in the neck at release.
