EVERYONE I FOUND THE PROBLEM.
I ran rclone sync
I'm fucking retarded.
rclone sync, syncs source to destination and deletes everything not at source.
so local disk has switched off at Aug 31st, I ran rclone copy, some time I ran rclone sync after assuming it would detect files that already exist, it did, and then deleted files that didn't exist on source.
literally as shrimple as that. So... media is gone between Sep 1 and Sep 5, sorry fellas :cirno_shrug:
What a stupid command
