I have a Character, which has a ChildActor component, and I have an Actor Blueprint with a static mesh. In a Blueprint I set the location of the Character, then disable physics on the static mesh, set its transform, and attach it to the ChildActor. When I do this in the editor, it crashes with the call-stack showing:
Fatal error!

The same code works in an iPad running iOS 8. When I remove the call to disabling physics simulation on the static mesh, it doesn’t crash the editor.
I have attached the part of the Blueprint causing the crash.
