I'm having problems loading & viewing some of the official maps in the level editor.
01_old_archives.map - The room with the lantern and 2 other rooms have no ceiling.
06_distillery.map - The two big rooms where you first see the grunt have no ceilings.
07_archives_cellar.map - No ceilings at all. Screenshot:
08_cellar_maze.map - No ceilings at all
12_storage.map - Many rooms and corridors have no ceiling
19_morgue.map -
CRASH when loading the map
20_sewer.map - No ceilings anywhere. Screenshot:
21_torture_nave.map - The whole area before the big spiral staircase is gone. Screenshot:
26_torture_nave_redux.map - The whole area below the big spiral staircase is missing but billboards & particles can still be seen althrough the cannot be selected. Screenshot:
This is what I can notice from just looking at them, some of the other maps may have stuff missing too. I've tried to reinstall the game and editors too, but that didn't work.
Attached is the logfile when I load level 2, 7, 21 and 19 in that order (19 crashes the editor), and the BlackBox log.
