Soft synchronization fails with additive loaded scenes

Hi trying to load a scene additive with NetworkSceneManager fails to synchronize in a build. It does work between 2 editors however.

Anyone else had an issue like this?

[Netcode] NetworkPrefab hash was not found! In-Scene placed NetworkObject soft synchronization failure for Hash: 2065433714!

Failed to spawn NetworkObject for Hash 2065433714.

NullReferenceException: Object reference not set to an instance of an object

Resolved. Allright after a lot of testing, I have determined it wasn't the additive soft synch at fault, it was having a network object prefab nested under another prefab that caused the problem. Just posting this here in case someone else has similar problem.

 

Same trouble bur don't understand solving. "it was having a network object prefab nested under another prefab that caused the problem" you got some network Prefab and another prefab inside it?

 

Figured my trouble. One of objects on scene(on client) got another acript attached so hash's of this prefabs were really different. I wonder if there will be many such "objectcs" with different hashes, how to figure which one have trouble? usually property "GlobalObjectHash" show different number non that on error
