Requires:

"never"

Dev note: In Vanilla, the flag 'f_ShaktoolDoneDigging' is set when on the right side of the room, regardless of which door Samus entered through. For the behavior where the flag is set by crossing to opposite side of the room, set this to 'never'. See also the related helper 'h_ShaktoolSymmetricFlag' which is logically complementary to this.
