Inherited AnimBP properties not always working across editor restarts

In 4.11 when making changes to node properties in an animation blueprint they will not always appear to update in child blueprint instances when restarting the editor.

In the attached project the loop flag has been disabled for the attack animation. If you start the editor and immediately PIE and then left click the animation will loop.

Opening the base anim blueprint (ThirdPerson_AnimBP) and recompiling will fix this issue.

I managed to make this happen again by flipping the flag, saving WITHOUT compiling and restarting the editor and going into PIE. It looks like there's a problem saving without recompiling.

If you compile then save the base blueprint the issue will be fixed.

1) Open MyProject.uproject from the attached project
2) Immediately PIE
3) Left click and observe the looping animation
4) Open ThirdPerson_AnimBP and look at the sequence player in the Attack state, observe the loop flag is disabled
5) Compile ThirdPerson_AnimBP
6) PIE again and left click, the animation will no longer loop
