In version 1.0 bug seen in the spring of 1967 - the crew of Gemini was blocked after the mission, with a note that he is a backup for a certain mission. Events such as the crew caught a cold, was not. The fall of 1967 the crew unlocked.
Supplement. Bug only appeared in the appointment of the manned Apollo missions in the spring of 1967. There was the option "no backup crews." If you appoint an unmanned flight - the crew of Gemini at number 8 is not blocked.
