I agree with XenoCow. If the tutorial creates an instance with the required amount of asteroids/materials, so only you can see/mine those, it is the easiest of the solutions in my opinion. It doesn't affect the economy and new players can continue the mission without issues.
Ha! I found some sunglasses! I just realized that there's a "camera" menu on top, where you can adjust "Ambient Light Illuminance" I set the first one on zero and the second on the middle and it helps A LOT in my case.
Hi! I agree with a continuity tester for pipes, cables, and ducts. I spent 1400 hours on the game and probably 80% of those on the designer; testing is so time-consuming -leaving aside the frustration of having to review all because of an unnoticed mistake.
Maybe ducts can report issues as beams do?
