Nope, nightsight works fine for me.

If you have that option set to 1 it prevents razor's filter that allows you to have perpetual daylight without the use of any spell.
If set to 0 you can toggle it on and off.
Neither of these settings prevent the casting of nightsight either by spell or by command.

Of course you can always make GMs exempt from this even so that it would not affect them at all.
