Recently, this plugin appeared in Studio:
This only appears if “Improved Constraint Tool” is enabled, and “Next Gen Studio Preview” is disabled.
I don’t think this plugin is supposed to be showing up here. And whenever I open a place, the plugin produces an error message:
Unable to load plugin icon: rbxasset://studio_svg_textures/Shared/InsertableObjects/Dark/Large/Bone.png
The plugin is trying to use a file that does not exist for its button icon, so it errors.
Additionally, the plugin itself produces its own script errors whenever you try to use it.

Repro
-
Go to
File > Beta Features. Ensure that “Improved Constraint Tool” is enabled, and “Next Gen Studio Preview” is disabled. -
Open any place in Studio.
-
Observe the error in Output.

-
Go to the “Plugins” tab and observe the broken “Bone” plugin.

Expected behavior
“Improved Constraint Tool” shouldn’t create a “Bone” plugin, and the plugin shouldn’t be producing errors.
