Photon View ID sets to 0 on new object in prefab.

Options
Hi all.
I have a big prefab on each scene. There are a lot of different kind of objects every scene needs to work properly. Some kind of scene manager if you like.
When I add new object with new Photon View, apply it to prefab, the Photon View on new object sets it ID to 0, unless I set it manually via code.
First i thought it was a bug for one of the objects, so I set ID via code and all was working ok, but today I've added new object with new Photon View and this bug happened again. So I guess every new object will have this issue.
This prefab is not instantiated on start, it just sits on every scene.
PUN2.
Please help me with this issue.
