Can not use weapons while being attacked orbiting planet or in galaxy area. Allies do though and so do your enemies somehow...

Allies ships do not increase in power as you do but enemies you attack seem to increase greatly in power. So your allies are smashed quickly and you are left fighting alone.

One small problem that I have in the space section is that whenever I reload my game the planets that I terraformed previously look like they've never been teraformed until I go down to the planet itself. Also, i'm not sure, but I think that sometimes planets revert back to their previous colors after using the planet coloring tools. Other than that, the patch pretty much took care of the main problems in space for me, though I would like to see more content.
