Description of problem:

consider chain before move:

1 -> 2 -> 3 -> 4 -> 5

and after move:

1 -> 3 -> 4 -> 2 -> 5

and planner log something like:

Move index (0), score (-30000), accepted (true), move (2(after 1) => 4(after 3)).

which may be wrong, I suppose move should look like:
(2(after 1) => 2(after 6))

It is not big issue or something, but some users might be confused by this as me today while working on nearby selection.
