Description

https://udn.unrealengine.com/questions/476212/race-condition-in-lateupdatemanager.html

 

In short, the trick storing a pointer to the packed index of the primitive does not work as it is simply a pointer into the same object as
the cached primitive already stored. If the object pointer is invalid, the index pointer will also be invalid.

Steps to Reproduce

See UDN post.
