I am playing ToA 2.02, and after my first two games I wanted to bring some minor issues to the attention of developers:
1. You cannot embargo minor races. If you go to 'Foreign Stats' and then click the 'Minor Races' tab, the option to embargo a minor nation is there, but you cannot select it. This is of some significance for the gameplay; sometimes a criminalist organization may appear and take your planets, for example, and so you might want to embargo them to allow for declaration of war without diplomatic consequences.
2. Oftentimes, when you sell a planet to the AI or the AI destroys a ship of yours, you retain the line of sight of that destroyed ship or planet for the remainder of the game.
3. If you successfully invade a planet with agents on it, or destroy a civilization on which you had agents placed, you lose those agents permanently.
4. The game crashes exceptionally often when the 'Dread Lords' event occurs.
