When i compile my map i get this:


^1ERROR: 'p7_eth_decor_01_rock_01' is not a valid physpreset asset

  physpreset:p7_eth_decor_01_rock_01
    xmodel:p7_toilet_bathroom

what does "is not a valid physpreset asset" mean?
Also i did a entity list search of all my models in map
i have the p7_toilet_bathroom in my map but not the
  p7_eth_decor_01_rock_01 is nowhere in my map!?

can this be fixed or its a radiant odd bug or something?
The map still runs and it finished compiling and all.
