So its always the court.mdl that causes errors then?
(if I understand your initial post correctly, it was a bit 'blurry')

with all the 'building' models you ent_create, you dont tell them to
go to the 'models' folder. By this I assume these models arent in it.
Is this also true for court.mdl?

This can sometimes be tricky, because I found in the past if you
are using WED, and place models from another directory, it places
copies of them to the game folder...
