Commented Unassigned: Loading edited save game freezes entire 360 [1786]

Hello,

I've modified my own character which is level 45, and transferred the new save game to my flash drive using Horizon.
When i load this "edited" save game the entire Xbox just freezes.
Am I doing something wrong, or is this due to having the latest updates installed for the game ?
Or.. maybe something else ?
Please help me out :)

Also, I used this video for editing guidance: https://www.youtube.com/watch?v=z1KHwRnlSxY
