Make silicons unable to unscrew the nuke

[Musketman12]

On the other hand, I've won many a syndie round for the crew by dashing in, unscrewing the nuke and tossing it into the crusher as a borg. Removing the ability to unscrew the nuke would make me and all the other frequent borg players very sad. It's fixing the symptom, not the problem, by screwing over players who have nothing to do with said behaviour.

I'm open to other options of stopping syndies from doing it but I can't think of anything else to stop them other than a rule stating that silicons can't do it.
