After further investigation, I was wrong, I assumed that I wasnt unsubscribed from everything due to the amount of mods I have, turns out I was randomly unsubscribed from them...

Yeah I checked the workshop folder and all the files had disappeared there barring a few, namely my ACE3 Optional mods(ADR-97, RHS, Smoke, Tracers), they needed a new folder in order for them to work so I just created new ones for them following ACE3's instructions for their setup. Im not quite sure how I attach any files though, care to explain? I did clear my download cache though.
