Many gears, such as the Dual Golden Super Fly Boomboxes - Roblox , utilized a MainModule named “MultiPurposeModule”, however, most scripts in this module are outdated and do not work anymore ( most of these issues are caused by them using old libraries that simply don’t exist anymore ) and simply break a lot of gears.
Fixing this MainModule or fixing all the gears referenced in the MainModule that do not function would let well over 40 broken gears function again.
While this would be great, I doubt Roblox intends to do any sort of maintenance to any gear. I think the marketplace team can’t wait to deprecate them.
