Just want to say its been fun watching the game evolve. 

I've ran into a issue were I cant play the game with the largest map and large sectors. 

The first play through in the .65 version I was able to play until tomorrow and then the game froze on unknown civ 10 and no matter how many times I reloaded or different ways to get the game unstuck it would freeze on the same week. 

When I tried a new play through I was only able to play for seven minutes and the game froze again on a different unknown civ. 

I've tried to delete all saves and start from scratch but keep running into the same issue when I play on the largest map. 

On the good news its awesome to see what you have done with the tech tree, simple colonies, being able to get rare resources without having to make a world a core, and the battles/invasions being more intense.
