i get this error when i make a door with origin brush… therefore i cant make doors in my maps… try using a prefab, maybe it will help 
ive got rid of all teh doors now, can anyone tell me where i could get a good prefab door?

- Make two brushes like:
- Smallest brush must have common/origin texture.
- Select both brushes, click on 2D view (right button) and select func/func_door_rotatnig.
