Adamant Mod Bug (and it's big):
I'm currently in a game against the AI. I've got only a 2-system sector; my home system, and a neutral player's home system. I'm set up as an Oxy/Rock race and the neutrals are Hydro/Ice. I've selected a one-planet start and Bad as Home Planet Value.
Both of us started on unbreathable gas giants.
My homeworld is a domed Hydrogen Gas Giant, with 16 billion out of 1279 million. The neutrals are on a carbon dioxide Gas Giant, also with 16 billion people.
edit: Oh, and one more thing: I was attacking these neutrals, and they launched 4 squadrons of 10 Orbital Fighters from their homeworld.
The picture kept facing upwards, even during diagonal movement. I've never seen this before.
