What were you doing before bug occurred: occurs often during all aspects of gameplay
Steps to reproduce: Hold down left click, and then release it while hovering over any GUI button. This causes all your weapons, fighting styles, and magics to think you’re still holding down the mouse button, until the next time you click. This happens whether or not the tool is being held when it happens.
