(Glitch no longer works as of 1.8.3 fun while it lasted.) Notable things (I observed)

Mother Moose and Charlie cat will be activated (I don't know if it doubles the AI lvl they are on)

no matter if they are disabled or not.

If the game forces your Cameras down, your A and D keys for Radar will still be visible,

Does not happen for Pal Percy.

If AI are activated they will play normally and will kill you.

The Dummies can noclip with Mother Moose and Charlie Cat.

The Tools you had (locking doors, Shocking, Simon Says) will not be available.

Farmer Felix is the only (I think, writing all this on a school delay) animatronic that wont kill you if your Tool for offense is missing (he just wont kill you at all).

I think you still need to right click to progress even though it isn't visible.

Instead of Custom Hour, Monday will appear after completing the tutorial.

Mother Moose and Charlie Cat appear to be more aggressive (usually being you can complete the night

before they even show up but they are moving a lot faster).
