Right now, Starbases are militarily significant in the early and mid game but easy prey in the late game. Most of the posts in this thread see this as a bug but it may also be considered a feature - forcing you to change strategy once technology advances to the point where Starbases can no longer defend themselves. Realistically, there is no way for a base to defend itself against a fleet of late game battleships - you need to intercept and destroy that fleet with one of your own before

I'm pretty sure they steal them. In a recent game I decided to go for a technology victory, even though I had close relations with all other civilizations and could have ended the game with a diplomatic victory. Around the time I completed Beyond Mortality, a new minor race appeared - Vegans as I recall. A few turns later, as I was researching Technology Victory, I got a popup that the Vegans had Beyond Mortality! I was only six turns from the victory (massive technology infrastructure
I like to play clustered galaxies and tend to build economy starbases where they will benefit several worlds. I build influence starbases in border areas where the AI influence is stronger than mine. I rarely build military starbases. I do fortify my starbases and find that they are a significant military force in the early to mid game but have to be defended with a fleet if you get into a war in the late game.
A small hull with a pair of Stingers represents a lot of firepower in the early game. A few of these will give you the dominant military. I put them in orbit around my most important planets to prevent a sneak attack. Later in the game you have the option of upgrading them using your latest technology. That can be expensive but it's a fast way to move your military back into the lead if you have neglected it for a while.
From a game play standpoint, I think it would be nice if players could design their own starbases, the same as their own ships. The SB would have access to any of the weapons and defenses you have researched plus mission specific modules like trade, econ, diplomacy, resource mining, etc... They could take advantage of advancing miniaturization technology and could be upgraded the same as ships to incorporate your most advanced technology. I also like the idea of a fleet management module allowin
In my experience the lower PQ planets tend to have more than their fair share of bonus tiles and the lowest PQ planets, 1-2, develop into at least PQ 10-12 with terraforming techs. It's nice to have at least one high quality planet for your econ capital but you can get by without it - just needs a different strategy!
The nice thing about upgrading is that you can keep basic, low maintenance hulls in orbit and make them state of the art warships in a single turn if the AI declares war on you - assuming your treasury can take the hit. It isn't particularly realistic but can be a useful strategy.
Many of us manage to play the game regularly and for hours at a time without encountering any errors. The problem would appear to be unique to your environment. Try using msconfig to clean boot the system and see if the problem goes away.
