Missing Placeable Appearances?

[Teric neDhalir]

I've been plodding through making blueprints for placeables with new models in the hak and have noticed a few entries that don't give a visible model. So either the hak is broken, my toolset is showing more worrying signs of flakiness, the model isn't visible because it's a walkmesh helper or collision solid or it has some other use I'm not aware of. Can someone quickly see if they can give a placeable any of the following appearances;

c_BigWallCorner
CA_CROSS
CR_BROKEN_01
CR_DIRT_01

and if not I'll put in a ticket with a full list.
Cheers.

Those don't show for me either
