I have a dropper attached to some redstone to auto eject items. The location of this in my world is at x:55 y:11 z:-127 (photo attached). When I am at my base in our village at X:116 Y:76 Z:-174, I can hear it clicking when it's operating. I've been in spectator mode for awhile trying to track this down and finally figured out where the sound was coming from. I think this was an old bug that may have returned.
