It wasn't removed, technically speaking. ROBLOX made a transition to the Accessory system, so technically speaking, any item you wear in-game is no longer considered a "Hat" to the code.
When you press the hat drop button, it looks for hats on your avatar and then puts those into the Workspace, then repositions them. But, if there are no "Hats" but instead "Accessories," the system will not do anything because, technically speaking, there are no hats equipped to your avatar.
TL;DR, they probably just need to update it. |
