Victory conditions and starting placement seemingly bugged

Even if you unselect other victory conditions, Cultural and Prestige will still trigger- those are the two I am aware of so far.  Also, even when selecting for civilizations to start far away from each other on large maps or above, they consistently will start close to you.  I've played just two games tonight on Large map and both times I had one civ (only selected 2 opponents) start literally next to me.  When you drop it to just one civ opponent, it'll sometimes happen though much rarer.
