Hmmm... testing things out.. I'm preeeetty sure it works in normal gameplay. At first, I was testing using Creative Mode's SuperRadar which scans a massive area all at once. When using that, sometimes it would chaos, sometimes it would partly chaos, and other times it would fail completely.
But then I tested using vanilla radars, since that would be what we would normally use to scan areas, and it seemed to work. Because radars are so slow, I wasn't able to extensively test, but looks good!
EDIT: It also works when exploring by walking lol.
