Hello, I have a problem with instantiating a prefab with netcode.
I get

“[Netcode] NetworkPrefab hash was not found! In-Scene placed NetworkObject soft synchronization failure for Hash: 1873015637!”

and

“Failed to spawn NetworkObject for Hash 1873015637.”

If you can help me that would be amazing. Thanks :slight_smile:
