How to fix up navigation collection without reloading?

[andre9349]

Hello. I have two navigation collections contains common entity inside. Atter I reloaded one of them, other navigation collection sill contains detached entity. I tried to fix it using ChangeTracker.DetectChanges() method, but unsuccessfully.
How can I replace new entity in other collection without querying database?

This looks like a bug. The navigation for the other relationship is still holding on to the detached entity, rather than it being removed.
