a)      If I am playing and I load a previous save (while playing) the ideology tree no longer functions properly

• Previous unlocks are no longer highlighted
• The buttons on the top left of the screen will not allow you to switch between ideology’s (you can use the little overlap boxes next to the bottom row of ideology’s
• The game will choose the next ideology in order from top to bottom then left to right

 Exiting to desktop and loading the game fixes this

b )      Building an ideology bonus building then destroying it allows you to keep the ideology points generated. meaning once you have enough ideology points to unlock the first perk in each tree you could max all the trees even with only one planet

considering by the time i get the +1 per turn ideology project  i can build and destroy a +20 ideology building per turn
