Environment

• OS: Windows 10
• Unity Version: 6000.0
• Netcode Version: 2.3.1
• Netcode Topology: Client-Server

Additional Context

Note this report could potentially be moot, as I am using a third party asset (https://assetstore.unity.com/packages/tools/network/smooth-sync-96925) that replaces NetworkTransforms that could potentially have caused issues. It did start occurring seemingly "out of nowhere" however without any changes to the NetworkObject configuration and architecture as far as I am aware.

Please feel free to close this if the usage of the NetworkTransform alternative makes this issue not a problem solvable by the NGO team necessarily.
