Unfortunately I kept getting crashes such as:

Script 'Game-Interpretr' line 1411: NoMethodError occurred.

undefined method 'expr' for nil:NilClass

and

Script 'Indivi - Portrait Variables' line 907: NoMethodError Occurred.

undefined method 'expr' for nil:NilClass

This was in Windows 10 fullscreen after the scene with Mabel where she becomes a maid. I stole her space outfit before she left the party, giving her spat shorts and pink dress that she ended up wearing as her work uniform along with the choker(maybe the overlap bugged it?). In doing so, I equipped her gear on my main character. 

The first error occurs whenever ending a battle in success, which force exits the game.

The second error occurs after a rest, also force exiting.

But that is still not all. Throughout the entire game, alt-tabbing or wndw-tabbing out of the game is not allowed. Window tabbing to other "desktops" even turns the entire screen black!

This game seemed pretty good, so it is sad these bugs made it unplayable.
