UMG:widget blueprint contained animated one can't be saved?

In 4.5, If widget blueprint A contained a widget blueprint B has animation within it, widget blueprint A can’t be saved?
If I delete the animation in widget blueprint B, or delete the instance in widget blueprint A, I can save it.
Here is the error info:

Can’t save
Graph is linked to private object(s)
in an external package. External
Object(s): ScaleButton_INST
Try to find the chain of references to
that object (may take some time)?

Is this a bug?

I’m having the same problem. I am using my own widgets inside other widgets to keep things modularized and the animations prevent them from being saved. I can’t package the project either.

I have tried to reproduce the issue and was unable to do so on my end. If you could send me a copy of the uassest that is causing the error I would be happy to take a closer look at it.

Hello ,

I gave it another shot and was able to reproduce the issue on my end. I have submitted a bug report to the development team.

Hopefully 4.5 final release can fix it.
