Project gets corrupted after moving from 4.61 to 4.7. Causes editor to cash on exiting

The crash happens on exiting or closing 100% of the time with my project. Also, when launching my game through USB to iPhone5 it says Launch Fail but if I click the icon the game will have been updated. It never happens when creating a new project. I reproduced the bug on my Windows 7 machine as well as on my Mac Pro. I have tried migrating my content into a new scene but that did not work. I tried renaming all my folders and manually fixing all broken links but nothing helps. This is a Blueprint, based game. I am desperate to fix this so I can update my game so I can move on to the next game but this bug has me stalled.

Hi Stache,

We will be closing this post in order to focus the discussion in one place.
