I'm assuming you're saying that you changed an svmap and it didn't update whenever you uploaded it to the client? If that's the case then this is because the svmap changes have to be done within the server files in PSM_Client/Bin/Data/Map. The game.exe doesn't read the svmaps in the client unless it's a recent game.exe that has the ability to tell the user where quest mobs are.
I would read more in the

thread to get a better understanding of how the client files work.
