Adding gameobjects

I have made one big gameobject.dbc including all original once that where in it and placed it in the mangos dbc map it has alot more stuff to .addgo ingame but somehow the objects stay uninvisible.But it says spawned.
Do i need to update my patch.mpq file in wowclient map /data also ?
And if so is it easy todo it ? because i have try doing it and saved the mpq file but as soon i start wxw it crashes.
So i must have done something wrg.
I would like to expiriment more with adding new scenery and stuff and remodify the complete server.

Can someone assist me in this ?

Yes you will need to update client side too,
No you probably didn't do anything wrong; it's just that WinMPQ can't handle files bigger then 2048Mb :-/

Actually i am using a program mpqediten32 that can handle more then 4gb
So i even checked the mpq file and compared it with the dbc file and all numbers are correct and dont miss any.

But when i start game i get message error in patch.mpq gameobjects
