I fixed the old “Gigantoform Potion” gear. The issue with it was that a module required by the resize script used LoadLibrary, which was deprecated by Roblox for many years before being removed outright in 2020.
Fortunately, in the DevForum thread mentioning this removal, a model was provided containing the scripts utilized by LoadLibrary, so I was able to use those to get this gear working again.
Here’s a .rbxl file containing the fixed gear, in case you want to try it out yourself and see the fixed code.
