Doomsday Engine

Since commit 4a17186db0e22a8a02494ea5d9c7ac492817254d ("Cleanup|World|Sector: Determine missing materials when classifying sector clusters") Hexen "crashes" on map "Heresiarch's Seminary" when player tries to enter the center of the seminary (temple/chapel/castle/whatever you call it). Reproducible quickly every time by:

warp 13
kill
then enter the building.

Tail of doomsday's output:
