Okay, it's Let's All Laugh at Crispy Time!
I was supposed to build a dock to land my ship at my HQ, but I couldn't figure out why the "dock" wouldn't actually line up with the outer ring of my base properly. The game still allowed me to build it, but it wasn't actually attached! It was sitting about 100 meters above the central asteroid of the base!
Why?
Because I told the game to build a pier (can accept size L ships) and not a dock.
It's okay, though, because I was able to fully refund it, not losing any of my building materials, and I only needed to source some local hull parts to build a standard dock which, of course, does align correctly with the base. Now I can finally enter it.
WHY DOES EVERYTHING HAVE TO BE SO HARD
I love it, though. My brian is 100% stimulated, even if I'm making stupid mistakes.
