[SetAsync]

Same problem, happens whenever you interact with a menu item to try and run a command.

[ChrisTVH]

I think this happens when you try to move objects in the inventory, because I don't use their menus or objects.

[ChrisTVH]

As of today they still don't fix it, I noticed that it happens when you open any menu even if it's not from the same plugin.
