Network RPC - exclude specific client

Hi, i have a setup with what i would call an authoritative Server.

There, client-copies on other clients are despawned by

GameObject.Destroy(this.gameobject)

based on Distance to each other (and spawned too. ..Some kind of interest management in background).

copies are synced with a networkview on each copy. But when i destroy a remote client-copy, the player still recieves the update-rpc's for this viewID, and respectively generates many error messages. how can i exclude that specific client from receiving rpcs for the destroyed copy? (other players may still need updates)

rpcmode.others is used from the on-server player instances to update the clones.

All clients and client-copies are created by rpcs (no network.instantiate).

SetScope may not be feasable, because of the limit and me having trouble managing that for the big amount of group-shifting needed.

Thanks in advance.

(P.S. instantiation works like this: client sends spawnrequest, server allocates ViewID, sends rpc(spawngranted,playerid, viewID), client Object.instantiates his copy. When the on-server intance enters another on-server instances radius they each spawn their copy on the other connected machine with their copies networkView set to their viewID. sync is then accomplished through rpc's)
