After extensive playing all of the bugs I have found have been posted here already, the game is quite robust and have never had a crash.
One minor one I have not seen posted yet is that on some playthroughs no enemies are generated unless they are placed for a mission (main quest, bounty and defend station), opening salvage that is trapped or generated at a factory.
I cannot work out why this happens as it happens on all difficulties and modes with different ships.
It is uncommon but it has happened about 5 times on mobile and twice on steam.
