Neighbors are not alphabetical, they constantly switch places.

I have always liked having the neighbor lists alphabetical but I was going through Zoo 2 and each time I return to the list to visit the next neighbor, the neighbors have rearranged in the list.

They are still alphabetical.

You have your list of unvisited neighbors, sorted A-Z.
Then you have your list of neighbors you have visited, also sorted A-Z.

The list of nbrs u have visited a-z will b on the bottom. The ones u haven't at the top.
