The rocks in the central room of "Mvelthngth-Schel, Heart's Wake" hinder spider centurion movements. The outermost rock is impassable to them. The innermost one can only be ran around from their right.

Maybe pushing the rocks a little will give them room to maneuver.

This issue has only been tested on OpenMW 0.48. May need to be reproduced on other versions or the original Morrowind engine.
