Ok, Two bugs to report and a comment

First, when your terraforming multiple planets, you cannot chose the same type of terraforming in the que twice.  Say you have two deserts and you want them to savannah, when you que them, only one can be qued at a time then you need to do the other.  If they are different types of planet,s like one to artic another to arid, the system works fine. 

Second, when your culture area clashes with the AI's, and the AI's is stronger they can aquire your systems and planets, but you cannot aquire theirs.  If your culture covers the AI's territory and you've got them the game locks, freezes or errors upon clicking that particular system.  So as of right now the AI can aquire your systems via culture and you cannot aquire theirs.  

Thirdly, I've logged close to 300 hours in the game on steam, love it, love the work you do and the game design.  However, playing on impossible, endless, or serious difficulty the AI ship designs seem to follow the same design ques.  They use simple weapons, and never really change throughout the game, I'm also pretty certain the AI leaves open hard points on their ships because the attack strength never really increases.  The AI needs to be able to adapt to my strategy and use the resources available to them to build better stronger ships, otherwise replayability will be lost.  Like if the AI has lots of titanium, so it researches titanium weapons and shields then applies them to its ships, or associate what the AI has access too in its cluster of systems and devolp its weapons and ships accordingly that would make a huge difference.  

As it stands right now the AI cannot beat a flotilla I have properly set up at 6 command points, when they are using 22 or if I have 10 cp, they have 30, I slaughter them.  It just seems like they are not using resources properly to design their ships and the attack power doesn't co inside at all with its technology vs attack power.  Look into making the AI ships design's better please, that would change the game and make the AI much more fun.  Great work so far cheers!
