Hi i have following problems:

First i havent found any way how to add ships into starbase defence ( tried guarding, sentry ). I moved my fleet into same spot where is my starbase but when enemy battleship attacks my base i see none of my ships providing defence.

The second problem involves colony defence. I have many ships orbiting my planet but when enemy makes his move against my planet i see that only one of my ships join defence. That gives enemy quite huge advantage ( being able to take out my ships one by one ! ).

I have played the game now only for few hours and i am quite satisfied except those problems.
