Rockets won't launch because they have an error saying "Missing Atmo Suit". This is a bug because the duplicants assigned to the rocket are already in atmosuits so there is no reason the rocket would need an extra atmo suit to launch.
Steps to Reproduce
Assign a duplicant in an exosuit to a rocket while your base has no extra exosuits to go around. The duplicant (that is still in the exosuit) will get into the rocket but the rocket will error with "Missing Atmo Suit" even though the duplicant is in the rocket in a suit.
