How would i completely remove an NPC from the game, both exteriors and interiors, in a way that he/she cannot be interacted with in any way by the player, but this will happen only at a certain time. And then at another certain time they will re-enter the world and continue their daily activities.
Any help will be greatly appreciateed.
Thanks!

I guess enable and disable should work.

This should remove them after 6 am and enable them again after 12 am

If GetCurrentTime > 6
disable

If GetCurrentTime < 6
enable
