To be exact, Studio will throw an error: This toolbar cannot create more than one button with id: “ID_Name_Here” and appears to happen 100% of the time. I’ve even gone ahead and made a dummy plugin with as simple as can be coding.
Video Example
Coding Example
local ToolBar = plugin:CreateToolbar("Empty Test")
local Button = ToolBar:CreateButton("Button","WIP","rbxassetid://2195531164")
print("This is a test!")
plugin.Unloading:Connect(function() print("Unloaded!") end)
When this occurred
Around the same update that allowed for plugins to be independently refreshed instead of needing to refresh the entire list. I’m not certain of the exact version.
It appears to not remove the plugins created toolbar or buttons, and for some reason, it will also prevent plugin.Unloading from functioning anymore (as shown in the video above). However, turning the plugin off and on will let it work again.
