[MERGED PR] prevent unscrewing the nuclear bomb from nukeops mode

[coolvape]

Yeah a currently very cheesy strategy involves "rogue the ai, have a silicon unscrew the nuke" - no need to even move the nuke after that, just being able to unscrew it and cut the timer in half is already absurdly powerful for nukies, made even stronger if they grab the nuke disk(admittedly, coordinating both those things is more difficult but it knocks the nuke timer down so much that the actual defense becomes very easy afterwards)
