Comment 2 for bug 1824362

If you had trouble reproducing this, Anton, I'm not surprised. I had to try 4-5 times myself just now to find a file that would do it for me. :-(

Here's a link to a video: https://drive.google.com/open?id=1tWBqG4JSWKHy-wKvSMJkyuoRfkrMNihj (The video is about 45 seconds, but it really stops changing after about 25, so you can skip the last half of it. Sorry for that. I couldn't figure out how to get the thing to stop recording.)

For whatever it's worth, the schematic I used to produce the video is here: https://github.com/virtualagc/virtualagc/tree/schematics/Schematics/2005252A. I artificially created a problem (not present in the linked files) by going into one of the child sheets and moving a connector pin (one of the oval-shaped symbol objects) away from the wire it's normally connected to.
