Fun at first, but as this is an idle game, it does get dull after a while. Fun to see how leveling goes if you just leave it on for a few hours though.
Further to last reported bug, once the rocket stops launching, it never launches again after that. This one makes the game unplayable, literally, I'm afraid.
Reload the game, it must help. Concerning the bug, do you have any ideas what cause this? Did this happen during the mission or after the mission?
