NetworkAnimator throws an error when the scene has NetworkObjects that are not observed by all clients (network hidden)

[TheCaveOfWonders]

NetworkAnimator throws an exception on the host/server when the scene has NetworkObjects that are not observed by all clients, for example if some clients have those NetworkObjects as hidden via NetworkObject.NetworkHide(clientId).

This takes place when an animation gets triggered on the server side.

[Netcode] Sending ClientRpc to non-observer! TargetClientIds contains clientId 1 that is not an observer!

Indeed it needs to check for observers and is not. This is a reasonably easy fix (should be done with all NetworkAnimator Rpcs). You should see this fix in the update after the coming v1.8.0 update.

@NoelStephensUnity Has this been fixed? I'm still seeing it in v1.9.1
