How do a Netcode build handle normal scripts? means scripts without networkbehavior

Hi i have a question about that. I have made a game almost finish now. I see that some scripts run double without Networkbehavior on it. Is this normal?

Thx for replay

Scripts without NetworkBehaviour are simply ignored.
For example, Mirror's NetworkIdentity class calls GetComponents.
That's all it looks at.
Every other component behaves the default Unity way :)

i have found the problem but good to now thx :)
