This may have been answered somewhere already so sorry if I overlooked it!

I uploaded a UGC-thing about a year ago and just recently went back to it to fix some recurring bugs and try and psyche myself up to actually finish the story. I edit and save it in the editor, then publish locally but when I go into SRR I only have a "publish" button which posts a brand new copy of the UGC with 0 subs, 1 view (me) etc. I have tried a really confusing (to me at least) fix that I found on the interwebs involving editing a .json file in /234650/Remote but to no avail :(

I would really prefer to just update my old one (for obvious reasons), is there a fix to this beyond editing this .json file? Hopefully something really obvious? ;)
