Description of Bug: It is possible to get through locked doors under certain circumstances by using pushing.
Reproduction Steps:

1.  A character capable of locking a door should close and lock a door while standing on it.
2.  A second character should push this first character.
3.  When the first character is pushed, the second character takes their place.

Screenshots:

 Don't have permission.

 In position.

Pushed through.

I can push again, to get through the door entirely, or just walk through if the other character leaves the space blank.

Still don't have permission.

Fixed.
