I was following second Blueprints quickshot pickup video which shows how to add a blueprint to an object.
I right-clicked object and selected add blueprint. When I right-clicked in Blueprint Graph Editor crash happened.
I think this same thing happened when I was using OSX 10.9.5 a few days ago as well but unfortunately when I tabbed over to video to get info, bug report tool locked my UI when I tried to tab back to it. For that incident I had to force shutdown because OS UI control never returned so bug report was never submitted because of another bug in report tool.
