GlobalObjectIdHash contains invalid if networked prefab was edited from Prefab mode #3151
Whenever I edit Networked Prefab in Prefab mode (double click on prefab in project tool window), then attempting to establish connection between server & client fails with:
[Netcode] NetworkConfig mismatch. The configuration between the server and client does not match
UnityEngine.Debug:LogWarning (object)
Unity.Netcode.NetworkLog:LogWarning (string) (at ./Library/PackageCache/com.unity.netcode.gameobjects/Runtime/Logging/NetworkLog.cs:28)
Unity.Netcode.ConnectionRequestMessage:Deserialize (Unity.Netcode.FastBufferReader,Unity.Netcode.NetworkContext&,int) (at ./Library/PackageCache/com.unity.netcode.gameobjects/Runtime/Messaging/Messages/ConnectionRequestMessage.cs:169)
...
If I edit Networked Prefab outside of Prefab mode (single click on prefab in project tool window), then everything works as expected.
This also server as a workaround. Toggling any property on a prefab in this mode "fixes" error.
In general if you check GlobalObjectIdHash property for prefab, then it's different between these 2 views.
My observations:
Main editor always reads GlobalObjectIdHash correct & consistent value (one from "prefab mode").
Virtual Player (via MPPM) reads GlobalObjectIdHash from "prefab mode" if last saved from "regular mode"
Virtual Player (via MPPM) reads GlobalObjectIdHash from "regular mode" if last saved from "prefab mode"
