This is a list of the bugs I have compiled so far. I don't know when they were introduced, could be in the latest beta build could have been in since release.
1. Galactic Guide Book doesn't work. After building it, my flagship was still the only ship able to explore anamolies. I thought perhaps I had to manually upgrade my ships to take advantage of it, but when going into the shipbuilder sensors still took space/money to place into a ship
2. Mind Control Center doesn't seem to work. I guess my sense of "near instant" defection could be off, but even with an influence ratio (the # in parenthesis) of over 20 it still takes years for planets to defect to my empire.
3. Cannot set shipyards to "nothing" from main screen. Very annoying. I have to go into the planet screen to set it to nothing. It does seem to switch to other ships with no problem, just has a problem with Nothing. In my last game, partway through it fixed itself much to my delight. Don't know when, may have been a reload after one of my numerous CTD's
