Procedure apoc.neighbors.tohop is broken

[kubaizak]

Guidelines

I executed procedure from the title on the graph given in the following example and when distance parameter is higher that 1 it returns strange result, including starting node.

Expected Behavior (Mandatory)

{name: "Mark"}, {name: "Joe"}

Actual Behavior (Mandatory)

{name: "Mark"}, {name: "Praveena"}

How to Reproduce the Problem

MATCH (p:Person {name: "Praveena"})
CALL apoc.neighbors.tohop(p, "FOLLOWS>", 2)
YIELD node
RETURN node

Simple Dataset (where it's possibile)

MERGE (mark:Person {name: "Mark"})
MERGE (praveena:Person {name: "Praveena"})
MERGE (joe:Person {name: "Joe"})
MERGE (lju:Person {name: "Lju"})
MERGE (michael:Person {name: "Michael"})
MERGE (emil:Person {name: "Emil"})
MERGE (ryan:Person {name: "Ryan"})

MERGE (ryan)-[:FOLLOWS]->(joe)
MERGE (joe)-[:FOLLOWS]->(mark)
MERGE (mark)-[:FOLLOWS]->(emil)
MERGE (michael)-[:KNOWS]-(emil)
MERGE (michael)-[:KNOWS]-(lju)
MERGE (michael)-[:KNOWS]-(praveena)
MERGE (emil)-[:FOLLOWS]->(joe)
MERGE (praveena)-[:FOLLOWS]->(joe)

@kubaizak
I was unable to replicate the problem, the procedure returns (p:Person {name: "Mark"}) and (p:Person {name: "Joe"}).
Can you try with the latest APOC version?
