Description of the bug

If you place a door, then place an egg right behind it, you can leave an open wall space on any side of the egg, diagonally, and it will attempt to hug the person through the wall. This can be exploited to know exactly when to open a door and get someone hugged. See video below for re-creation.

What's the difference with what should have happened?

hugger egg should not be attempting to hug someone in an open space diagonal to it.

How do we reproduce this bug?

1. Plant an egg
2. make a door below it
3. surround it with walls, but leave one or all of the walls open in an X shape.
4. open the door as soon as the egg opens and get a free hug.

To re-iterate, as a human you basically can't tell what is coming, and the xeno knows exactly when to open the door because the egg opens.
