UE4 crashed, foliage is unselectable now

I tried the copying solution, and it didn’t work, the landscape still says there is no foliage. And I have been opening auto-backups since my crash, and getting the results I posted above - incomplete messes, that have a crazy amount of inconsistencies between each file.

For an alternate backup system, is there a way I can actually backup the PROJECT file rather than just the maps? That seems like it would make WAY more sense, I don’t understand why this is not the case already. Any other program, 3D or otherwise, if you open from a backup, everything is EXACTLY as you left it when the backup occurred, so why is UE4 different?

Thanks
