Question 3 (possible bug): Abundant habitable planets seem to be bad/broken in 0.61, I've selected this option in several games the first 18 stars I came across only 5 had habitable planets one of which had 2.  To me abundant habitable planets should be 1 on almost all stars with several with 2, 3 or 4?  Am I incorrect?  This appears to be an issue where it's set to something else for one game you exit to menu and go back in change to abundant and start new game it doesn't apply correctly to the next game.

Question 4 (possible bug): Abundant anomalies also seem to be broken in 0.61, Also selected this where with in several turns of my home world I have only come across 1 anomaly.  I would imagine this with rare or uncommon, but abundant I should have no problem finding one at the beginning of the game on almost every turn.  Maybe this will change when anomalies auto spawn throughout the game.  (This may be part of the same issue that effects the above issue)
