it could also be nice to see them having a routine
they all could walk around in safe mode but if its their night they turn hostile
the dev could make 1 night per charcter where that girl turns hostile
then 1-2 alt nights
1 where half the girls turn hostile
and then a nightmare mission where all of them turn hostile
but i do think if the girls have the same bug the normal fnaf has where they walk around at night you should keep them on the map in safe mode
