Yes, I have the BTRoblox - Making Roblox Better Extension, but I tried turning it off and the bug still occurred. I have no other Roblox Website Changer Extensions, or Modifications.
This bug seems to occur when I click the member category button, and If i were to fix it, it seems the button gets moved to another area on the website, like in positioning.
When this happens, it gets hard to press the button again, almost impossible.
