Expanding on issue #48, when chips don't have an input and an output, not only do connections from such chips get lost, but in my experience, some gates within those chips cease to function entirely. I've created a 2 minute demo video showing this bug in action. I could be wrong about the reasoning for this, but I don't believe this to be the case.
What I neglected to show in the video is that, upon viewing the chip, the OR gate, assuming it had any signals being sent in, would also not provide an output unless I deleted it and placed a new one.
Edit: I've replaced the video link with a rendered version so that the audio track for my microphone is included.
