I recently finished wiring my control panel for a 4 player setup. Everything works great except for one issue.
A button is not firing if it is pressed immediately following another button. If the button is pressed anytime other than right after the button it will register.
Ex. Button 4 works if pressed anytime other than after Button 3. If Button 3 is pressed Button 4 fails to register the first press, but will register the second press.
Any idea on what I missed?
