Seems to me like it would be your combine resource. Or it could be your item resource is screwy.
If you have not done anything but restore the server files then the first thing I would suspect is the match of your client to your server files.
Are you sure it is the same version as the server files and if it is then you may have to
perform some resourcing techniques in order to repair it.
Try Smokes grimoire tool he created for client server management...
