Strange console error

[JosephD53]

Every now and then in HL2 RP, I get an error in my console saying something along the lines of: Error Vertex File for 'props_wasteland/exterior_fence002a.mdl' checksum 436995265 should be 436994449 . I don't know what the error is or why it is there, but it slows down my FPS drastically.

con_filter_enable 1;con_filter_text_out Vertex
That filters every Vertex error
