Thanks for posting your trouble with downloading the stages. As it turns out, the Onedrive account I had hosting the downloads was frozen, because I am over the free 5GB quota and they finally decided to reprimand me for it. At the time when I uploaded the entirety of the collection, free users were given around 15GBs, but then about a year ago or so they reduced it to 5GBs.Today, I was able to unfreeze the account and the files will be available for download for another 30 days.
On 07/28/2017, Microsoft will delete my Onedrive files, and in turn I may have to delete this collection topic, unless another user wishes to upload the entirety of the collection on their own storage and edit my topic by replacing the download links for each stage. If anyone wants to get a jump start and begin replacing the links let me know, so we can save all the hard work that was put into making this collection available for everyone, but more importantly to help preserve the largest collection of stages from Mugen's #1 stage creator of all time.
