[4.7] - Blueprintable Component causes "Graph is linked to private object(s) in an external package" while saving a map
I found only one annoying workaround so far. Remove BP Component from actor, save actor and map. Insert this BP Component again, save actor and map. No errors.
Could be related to https://answers.unrealengine.com/questions/179442/470-461-inherited-macro-causes-graph-is-linked-to.html It's similar nonsense ;)
I could provide more detailed repro and/or some files, if this would difficult to replicate. But it looks like common issue in fresh system of Blueprintable Components.
I've had this issue several times. It is usually followed by doing something it didn't like. For instance, undoing something that was deleted. I am fairly certain at that point it is a corrupted BP and will need to be remade. I have seen this in 4.6 and 4.7, though 4.7 seems to have more crash bugs at the moment then Window XP.
I have had this issue come up and i think i know why this error happens. First i will ask a question did any of you copy the component or duplicate a component?
i had this error about a week ago so i deleted a component until the save error went away then recreated them , and no problem.
i just had the same error about 5 minutes ago , right after i duplicated a static mesh component. so im pretty sure if add a new component instead of trying to duplicate one you should be fine. .....
yup thats it i was just able to recreate the error again.

I just got this same error I copied components from one blueprint put them in another and re-named them however it apparently still tracks some data from copied component.
My Solution: Delete all copied components and re-create from scratch
