Should I mantain Cloning Bay powered when traveling?
When traveling through space you can encounter some events that kill some crew member, but having the Cloning Bay you can (sometimes) have a special option and "resurrect" them at the end.
To have the opportunity to do that is necessary to have the Cloning Bay powered with at least one power, or I can have it unpowered an still be able to have the "happy ending"?
Solution 1:
It's safe to leave the clone bay unpowered. If it can save a crew member after an event, it will.
The cloning effect from events behaves like any blue event- it only checks the presence or absence of a system. Whether it is powered/damaged/on fire is irrelevant.
