(mod) CenterOnCell places player at the last DoorMarker instead of first
Vanilla seems to direct CoC to the doormarker linked by the earliest cell in the load order. OpenMW instead seems to direct to the last one.
coc "ghostgate, temple"
Vanilla puts you on the side of "ghostgate, tower of dawn"
OpenMW puts you on the side of "ghostgate, tower of dusk"
Similarly coc "ghostgate, tower of dawn" puts you near "ghostgate, tower of dawn lower level" in OpenMW, near "ghostgate, temple" in vanilla.
The title is not quite correct. OpenMW's algorithm works by looking at the first teleport door in the interior, following that door outside, then following the first door back into the interior to get the spawn marker. This is arguably much faster than scanning all cells in the game.
