Auto saving not working and BP's gone missing

Error saving ‘F:/recovery 27.11.2018/Josh y2/lightingbriefv4_21/Saved/Autosaves/Game/FirstPersonBP/Maps/FirstPersonExampleMap_Auto1.umap’
The problem I’m having is somewhat minor in the fact i cant still save my file but for some reason auto save does not work, I’ve tried closing the program down and re opening, also I’m not sure if this is having an effect on me trying to back up the files with a simple copy paste in another hard drive. (note: i have not made a back-up yet so the file has remained in the same place since the start of last week)
In addition to all this I noticed this morning 3 Blueprints i made have gone missing completely but with one still having the icon of an empty actor in its place, and all it says is asset missing failed to load.
This last one is the most worrying because I’m in the middle of building 3 different types of Ai and if this happens to them during my brief for uni its gonna be detrimental to my grade.

Note: I’ve solved the auto save issue and backing up problem by just migrating the files i needed into a new project, not sure about my missing blueprints thou… i think they just got corrupted somehow because in the first migration attempt
it crashed and made the game unattainable.
