I did make a snapshot as i wasn’t sure if Epic needed any info.
The size of the snapshot for the false memory is 486mib and the normal is 47mib
I cannot see a size assigned to anything rather a list of things so its difficult to determine what caused it or rather what changed
It was something with the level. Somehow is doubled just by starting a session on console.
If they is any logs ect that are required i will assist where i can as this could have been a major issue if i didnt have that snapshot. I only lost 5 hours work so its not the end of the world but it could have been alot worse
Just to add i did do the HLOD after the first snapshot so i can do that again save then send to console and see what things change 
itll take some time but ill do it
