Known Bugs so far:
-when spawning on one of the celestial bodies in sandbox it will spawn the ships huge distances out
-sometimes the rings of planets show up behind the planets or are just in the distance
-crashes sometimes?

On the "nuclear retaliation" mission, the allied fleet is a ship I made, and not one equipped with any nuclear missiles. I was able to beat the mission anyway, but I'm guessing that's not intended as the mission doesn't have editable fleets. This mission also crashed a lot trying to get intercepts.
