The first thing was I built a construction ship in 2 different places. Whenever I tried to build a starbase, the game crashed with both of the ships. This happened with both of them continuously. I was able to only use them for upgrades on existing stabases.

The next thing was I was unable to attack a planet.

1) I had researched planetary invasion and was researching planet bombardment.
2) I had built a freightor class ship with 2 troop transports on it.. It did say transport troops on the special abilities section.
3) The planet had no enemy vessels nearby.
4) The planet had a red skull and crossbones on it (in revolt)
5) When I sent it onto the planet (right click) all it did was set there with "no destination".

Did I do something wrong?

PS. I tried it again with a "stock" transport and as soon as I got there the planet flipped to me.
