Is it intentional that the 200 tick upgrade blocked after a nuke lands, when extended with attack controller, still allows safe mode? As far as I can tell even if keep the I keep the controller upgradeblocked on every tick safemode can still be activated on the 'reapplication' tick.
An example of my trying to prevent safemode by attacking the controller to no avail can be found here https://screeps.com/a/#!/history/shard1/E1N28?t=10033961
It seems there was no tick that was not upgrade-blocked. Or should I just coordinate my nukes better?
