So I was in the middle of a very long mission, and was running really low on HP and any food/stimpaks/water etc.. It was in a location where I couldn't just fast travel somewhere to stock up on medicine and come back (won't tell more to avoid spoilers).
So my only choice was to load to an earlier save from before the mission. I quicksave very regularly, but in my save data there were only my last 4 saves (all within the mission) and a few saves from like 3 weeks ago..
I thought well [censored] looks like I'll just have to fight through this mission somehow. BUT then I ran into a bug that prevents me from getting any further in the mission.
So basically I'm stuck in a location, can't fast travel, can't complete the mission, and can't upload a save from before without losing 3 weeks of progress.

Any ideas what I could do to fix this? I was very close to completing the story line so not feeling like starting over

Hopefully my explanation is understandable..

Forgot to mention I use ps4 unless that's obvious from the section lol.. I might seem a bit dumb but I just don't know that much about this stuff I've never had any problems with save data before.. Is there a way to see individual saves on the ps4 other than by choosing 'load' in game? I want to see if there really are only those 8 saves in my fallout 4 save file :/
