Even though its for an older version, maybe someone knows a workaround (want to stay on 1.3.1 because of mods)
When I enter the Astronaut Complex no crew is displayed and it shows 10 crew members of 12 assigned, even on a new game.
KSP Version: 1.3.1.2077 (backdated from Steam), same on 32bit and 64bit version (Windows 10), clean install
Steps to Replicate: (start new game) and enter astronaut complex
