Okay, I'm playing a game where I am a custom race. I built a military station, then upgraded it. However, it seemed that the base station was just stacked on by the upgraded version. I didn't think much of it since it looked cool.

Now, I'm at war, and they attacked my economic station. It won, but now has a double of itself, and the military station is just gone. It wasn't even attacked, but it's gone.

Here's a pic of the double station:


It should only have 4 arms, and before they were more stacked on each other.
