Yes! Once power is restored, the computer restarts, and the timer is set to every 15 minutes out-of-game! I could have been more clear, it IS a bit complex, but I hope this helps!
Wherever it mentions 'rounds' out of combat, eg 1d10 rounds to repair the generator, what duration is that? Mothership doesn't define rounds other than 10s combat rounds. Were you thinking 10 minute adventuring turns like D&D?
Usually, when out of combat, 1d10 rounds indicates the number of encounter checks the Warden should make as the action is being completed. Hope this helps!
