I am playing a game with version 1.04 and have a save that demonstrates a couple of issues, but the primary one is an issue with a battle that takes place, but afterwards appears to have not taken place. The save is located here:
After you load the game go to the planet named "Dratha". You should see something like this:
The first problem (a minor, but annoying one) is that you cannot see my fleet of 12 ships or the anomaly I am about to attack, so you will need to zoom in until it looks something like this:
The second issue (also a minor one) is that you can see the ships defending the anomaly (sort of).
If you select the 12-ship fleet (which does not have a surveyor) and use it to attack the anomaly, you will see a battle, but there will not be a window showing the results of the battle. You will also see that, while the anomaly still shows a "3" indicating that 3 ships still defend it, you no longer see the defending ships, as shown in the following screen snapshot.
If you hover over my 12-ship fleet you will see that it has not been damaged and still has 12 moves left as shown in the following screen snapshot.
I think your coders need to figure-out what is going on and fix this. Hopefully, the saved game I have provided will make their job a little easier.
