Hey fellows!
So I was playing SOASE over LAN with one of my friends, and we noticed the weirdest thing. All of a sudden, we were playing entirely separate games. We aren't sure exactly how long it was happening, but at some point it became obvious we were in entirely different games! First, when I removed some extractors so he could take them, they never left for him, and we actually figured it out when some pirates took a completely different route in his game as compared to mine. At this point, it was nothing but a normal desync. It happens, and we didn't notice because we were playing in the same room.
What makes it REALLY WEIRD is that some things still translated from one computer to the other! For example, when he offered me a Diplomatic pact, I could still receive it and the pact worked normally. When tested, we could still see each other's chat logs and each other's pings, for example. But each others' ships were under AI control!
We tried going back to an autosave, and it immediately suffered the same desync. We could communicate, but my actions didn't show up on his machine.
If it helps, I believe the desync occurred at a save, because when I looked at things in his game, it was about what an AI would do with my ships from the point of the autosave.
