MCC Halo: Reach Content Bug

On 03-15-21, I randomly lost four Halo: Reach Forge World Canvas Invasion maps that were 100% completed and were going to be tested this Friday, I am affiliated with a MCC Forge/Custom Games Discord Server. The maps were named; Dockside, Unscathed, Unruly, and Daylight. As a Console player, I remember this stuff happening back in early 2011 and how devastating it was. Is there any way I could have these maps recovered and placed back into my file-share?
