Bug With Pack #pragma

Hello,
I spent Friday and the weekend tracking down a very strange problem where variables in a child class were completely independent from variables in the C++ base class. A video describing the bug is available here because it exceeds the upload size:

And I am also attaching the debug project where I narrowed down exactly where the problem is, excluding the Content folder due to size. The contents of BugTest.sln/uproject for me were \Desktop\DeleteMe\BugTest. Please let me know when I can remove the video from DropBox.

Thanks!
