Update lost my forge map

Hey, I have been working on a huge forge map for Halo 5, and I have spent a lot of hours today working on it, I have been saving like every 5 minutes, call me paranoid playing forge online, then when the update went live the game kicked me out of forge, and I left to install the update.

Finished updating I came back into halo 5, loaded up my map, and about the last 6 hours of work on my map has been undone, despite all my saves, the game even told me it saved itself before it booted me from forge.

Really wondering if there is anything I can do to get this progress back. I saved my progress so many times during the day I struggle to see how its decided to revert back because of an update.
