Are Thalans not supposed to be able to put battle stations on their starbases in Twilight? I noticed the techs for these modules being on the hulls tree, but none of my starbases could apparently have battle stations installed.
I've played a game as Yor since then, might try another as Thalan soon. Using starbases is a lot harder when they don't have any defenses.

Also finding the lack of space mining/economy modules annoying, but I think that was a development decision.
