Here are a couple of quick things I saw in my latest game with B2:
- Planets are listed sometimes in Stacked Ship info box. Occurs typically when a freighter is over the planet.
- Not sure if this is intended: Space miner does not start to build a new mining base automatically when sent to an asteroid field more then one space away from its present position.
- First Duranthium Armor tech is in the Titanium Armor research group.
- When double clicking to launch a ship from orbit the ship is not selected for movement. Clicking a square to send that ship actually gives the move order to the previously selected ship.
- Not sure if this is intended: You can use the same 3,6,9 spies to increase your espionage level with all races. Simply place 3 on one planet, then remove them after you get the LOW message, and place on another planet in a different empire. Rinse repeat for all empires.
- It is sometimes unclear which tech out of a grouping leads to the branched tech. Case in point the Diplomacy to Counter Espionage tech relationship.
And who ever came up with the segmented tech groupings to clean up the tech tree deserves one heck on an *atta boy/girl*!

Makes that screen nice especially with the long weapon branches.
