Alright, I think I got this. HD episodes will be uploaded to Zippy via unbounded by an account from then on out. I'll be checking the links weekly to weed out any dead ones.
SD episodes are slowly being reuploaded on other accounts. RS is first (since it was the first MF folder to get nuked), then AT and lastly Gumball.
In the mean time, enjoy this week's RS in HD!
EDIT: The HD version of this week's AT is now available, along with the fixed SD version.
