It works different of the other fatigue systems.
is a non recoverable "fatigue" ,..is a combat stress.
I´m trying the rub fatigue system,
The problem is when the aceleration time is used below 32x. they become fatiged and is impossible recover the crew, i always left a quarter filled of fresh peoble as a backup for the engines room ,and i replace the crew when they are fully stressed and are unable to use the engines.
but is a problem with combat actions in low aceleration time.
the torpedo room stress a lot the crew,.. remove it of the compartment unless do you want to reload torpedoes or they could be stressed.
