VC:MP - Annoying BUGS

[(vG)DesTroYeR^]

BUG [1]:
HideMapObject(ID, floatX, floatY, floatZ);
I used this function in my server to hide [construction site #1], but i had discovered that the textures are LOD, they can be seen but 'PERMEABLE', which means that the function does nothing for particular objects, this has to get solved.
BUG [2]:
Generic.TXD
I am using it in my server to hide the exaggerated trees, it also purifies the vision, but sometimes, the textures (streets, trees, or maybe bushes) wholly turn into white, and sometimes they turn into 'BUILDING' textures. WTF.............
BUG [3]:
Vector()
Misusing the vector function is bound to crash the entire server, for example: player.Pos = 0; player.Pos ++; player.Pos.Distance(integer); ....
