Hold Ctrl and Shift, and click on Small Constructor to start creating 1000 Small Constructors. Watch the progress bar moving to ensure they start creating. Close constructor. Open the constructor. If the progress bar is not moving, wait for the current item to complete and you see the progress bar moving again. Hold Shift and click on the Small Constructor under construction. The progress bar will jump backwards then start moving forward again. This bug seems to happen with any item, but easier to see with items that take a while to create.
