Short description of error
Don't know if it's a bug or a feature. When you do a full copy you expect it to be a full copy, but particle settings rather stay linked.
And what's more, it should assign the copy of an instantiated object from the new scene. Well, I suppose it should work like that at least.
Exact steps for others to reproduce the error
Open the file.
Do Full Copy.
Particle settings stay linked.
