Chances are that the save procedure is being called when the client already left (which makes it null), ex: client/Del() or mob/Logout().

No problem, that's like the downside of client-side saving. Maybe you should make a force-save when something important happens, such as passing a quest or leveling up.

It is also a good idea to have safety checks in place: 
client/proc//_Whatever_The_Name_Was
   if(!src) return // If the client does not exist (is null), nothing happens (stops the procedure from continuing)
   ......your other stuff here.....
