I strongly suspect these bugs have already been talked about and Stardock knows about them.

1. Altarians cannot progress past the first Approval building because they cannot build Entertainment Centers from the Enjoyment tech

2. If you start a game after initially loading the game, the tech tree is fine (here is Altarian tech tree):

However if you load a saved game or you quit an existing game and start a new one, the tree gets messed up, compressed:

Functionally, I'm unable to research Precision Manufacturing because it is actually in Age of War despite what the last screenshot shows. I encountered the same kind of problem on the Terran tech tree when trying to research an Age of War farming tech. Gave me about an hour of frustration trying to figure out why I couldn't research certain techs.
