I've been re-organizing my runtime and installing content I downloaded over the last few years. I noticed that in my Miki folder is a "PART" file from when I tried downloading the SR3 update back in 2017. Problem is, I don't know where to find this file now. Miki4 is now for sale here as legacy content, but since I didn't buy her here how can I get the SR3 without buying the whole figure? Where would this file have been hosted in 2017?
