Double doors in graphical version sometimes spawn perpendicularly

[macksting]

This seems specific to double doors, that is to say doors two walls deep. It makes no difference in their functionality, but often one seems to spawn sideways.

This is in a tower.

This is in a mansion.

I think it happens anywhere doors can run two walls deep.

Can't remember most of the other specs, but feel free to ask.

Hey turns out it also happens in single-wide doors in the ruins under Kist.
