This is a good workaround, however what I’m worried about is how people visually see the accessory when they go to buy it. Most times, people will check how an accessory looks on their avatar, and just seeing it being fully off-center may stray people away from buying it.
At this point, it’s mostly just the fact that roblox staff seem to ignore this bug, and could at least update documentation if it was changed. However, this would make no sense to me for them to still allow you to select the Normal and Slender proportions without getting the error that they dont exist. I still get the error that a proportion “does not exist” when i try a random value like 12345.
Hopefully, reviving this post may bring more attention to it, even considering the fact I was ghosted in my messages 
My UGC profits have been tanking as I rely on these low shoulder accessories since they are the main attraction for my group. I will have to settle on making other stuff for now, but I would really like to continue! This is mostly all my income in real life right now
