I just started a game with this version and was overrun by spirecraft in the first 20 minutes.
As in the asteroid-built stuff? Or the bonus ship types? And was it a wave (advanced logs?) or just stuff wandering through with no warning?
It was the spire maw and spire tractor, and it was quite a bit of them (probably like 5 of each would come through every minute), along with other random stuff. They were just random ships filtering in, and not part of any kind of wave.
