I just logged back on to Destiny after changing my gaming setup. I completed the Lightfall campaign at least on my titan and hunter accounts, I'm not too sure on my warlock but I believed I did. I went to school, upgraded to a nice PC, and when I logged in I lost all my progress on the campaign for all of my characters and lost all of my subclasses. This especially doesn't make sense on my hunter class (my main account) because I have over 30 engrams waiting to be decoded. What happened to my accounts and all the progress I made? I tried signing in and out again to update my progress, but I can't find any of my old stuff. No weapons or anything. I really don't want to go through the entire campaign another 2-3 times so if somebody could help me get it back, I greatly appreciate it.
