well *raises drink* heres to hoping someone responds....

i've been messing with the IDE files in the map directory of san andreas and i beleive they basically tell when to draw objects in the world. Anyway, i've been messing with the LA one, which is los santos and now i keep falling through the roads. If anybody could tell me what is causing this it would save me a lot of tedious work. If anybody has an information they could tell me about the IDE files in general would be great too
