Random position of notes

[alex3305]

When moving notes in a relative 'large' list (10 - 15), the notes magically resort themselves. It doesn't matter whether I move the notes in the affected list or not, they just resort themselves.

Addition: a diff of when I moved a note in lane 2.

Edit: It seems it's not random, but that when the values are stored, there is one added or something. Check out the post method of the positions...
