Not very long I was working on my project and I randomly saw the forgotten gear called "Goala Cola".
So I tested it for fun, then I converted the entire localscript into basic script and replaced "Hat" with "Accessory" here (basically modernized some stuff). And whoa, look at this, It used to replace a user's accessory with a hat called "Shirt Over Head" (according to its mesh).
So it means it's still working, but it got some broken because it's deprecated thing.
On the image, you see the "Shirt Over Head".
Not claiming that "Im the first who found this!!1", just saying.
