I don't really see any other problem beside the coordinates. I tried to go to the coordinates: 1590.9293,1762.1729,12.5320 and it is inside a hospital in las venturas. And by inside i mean that you fall down.

Try replacing them with 1582.5271,1761.8899,10.8203 wich are the coordinates of the entrance in the hospital.

Also i hope that you have mapped an interior at the coords -204.4959,-1735.3291,675.7687 because when i go there, there's nothing, so you'll fall down.
