Remember, it was Halloween last night - maybe your schematic is haunted!!
That is very weird - never noticed it happen before. I thought at first maybe preset manager, or a rogue wireless link - but no, it is the knob's float output connector that seems to have mysterious powers. You can even disconnect/reconnect from inside the knob, or rename it, and it stays stubbornly linked to the code 'streamin'.
You should send the schematic to admin, that's definitely a bug!
