I despise this game. It came from hell. It is really fun. But maybe you've done everything there is to do in the game. Maybe you want to build stuff that looks cool or mirrors something in real life. Maybe you want to do an Apollo replica. So you build a lander (a very cool one) and move it over to subassemblies. But It says THE SELECTED PART IS NOT ATTACHABLE. Could you explain why instead of yelling at me? No? Ok, screw you.
But I give it another chance. I work around the issue. I launch. I perform an encounter burn. I dock to the lander. I get to the Mun. I undock. I try again. And again. You see, it's kind of hard to enjoy this game when I can't undock. I hit the button. Nothing happens. The button DISSAPEARS. Now this happens all the time. Sorry Space Station, Mun Base, etc., you are worthless now.
Then I look at their update history. I then find out they are on a "much needed vacation" after working for an entire YEAR just to put a stupid encyclopedia that helps with nothing into the game. I promptly went insane. REALLY insane. I hate this game.
