I fixed it a long time ago, about a week ago.
http://www.fpsbanana.com/maps/16185
Latest Version, added clips to the map, optimized it, and added much more features, please test it!
I get +60FPS on it on full detail, (was on 40FPS before)... Which isn't bad, but i'm still optimizing it, it should be quite playable now though, should get around 60 constant with 20+ humans(no bots). Map has been sealed completely so you can't fall off, first house has been opened, widened vents, edited props for gameplay, added another unground near CT spawn, add a ZM version with buyzone and new T spawns, please test.
The map name should be ZM_RAYNERBREAKOUT5, Or ZH_RAYNERBREAKOUT5, I already have a ZH_RAYNERBREAKOUT6 and ZM_ on the way. Will upload tommorrow, in the mean time, test this version!
NOTE: At the moment the file mirror which I uploaded it to isn't working, so right now I am re-making the ZM_ version and uploading it, should be up in, 5 minutes.
*EDIT*: Map done, just compiling them both and uploading now. =D
*EDIT*: Done compiling, uploaded zm and zh versions 6.
