When I sent a freighter towards a Drengin planet, the Drengin responded by making a trade offer. They offered to give me a starbase mining anti-matter for no apparent reason.
If I accept their offer, the game crashes.
I purchased all trade goods from the different AI, thinking this would make my trade routes more lucrative however I couldn't verify this because opening a trade route leads to the trade offer and game crash.
A lot has changed with the game's appearance notably the ressources in the game it's shaping up nicely.
The AI behavior also seemed strange to me. A minor race demanding a tribute when they didn't have the military to impose it and the Drengin demanding I give them a tech when I had colonized or conquered most of the worlds in the game except those belonging to the Drengin.
