So after the 119th update you found a whole load of textures disappeared, some useful poster overlays, some paint patches, dead lilies, windows and some doors.. I talked to some people at valve and they're looking into their removal, but until then you can perform a simple edit on the tf.fgd file to get them back. First locate your tf.fgd in sourcesdk\bin\orangebox\bin\ then right near the top is the material exclusion bit. Just comment out the lines with cp_bloodstained, pl_hoodoo and pl_halfacre. That will redeem all of the useful textures from hoodoo and keep the blasted ambulance texture safely locked away in oblivion. Now you can get back to using those textures.
