SV_SetBrushModel: NULL error

[Navras]

Well I was testing my map fine and I had just put in teleports (it was working fine before this) and I compiled it and went to test it but I'm not getting this error message when I try to load it in tremulous. SV_SetBrushModel: NULL

any ideas why? I have deleted the teleports since then and it still has the error

It means you have something(ie a door) not attached to a brush
to find it, press l, and go through the list until you find one not attached to a brush, then delete it.

It also proves you are incapable of using the search function that is so usefully provided.
