I found a ship, the "Demolisher" when I completed an expedition to some ruins. The ship's icon appeared distorted, like part of its texture wasn't loaded, as shown below. It fixed itself when I exited the game and loaded the save game. I am not sure if it is a specific issue with this ship or just something to do the state my game ended up in at the time I found it.
I also just took the Demolisher into battle and it has no movement range apparently. EDIT: If I overload the engine, I was able to move it just a little bit.
The second issue has been fixed. The Demolisher now has more combat speed. As for the first issue, we've seen that before, so it's not solved yet. We'll take a look at that.
