Relative Loop Tween Bug?

[Secretmapper]

 

This results in a weird tween in my game (player.y = 55):

        this.game.add.tween(player).to({y:'+5'}, 250, Phaser.Easing.Quadratic.Out, true, 0, 100, true);

In that the sprite jumps around. While this works as intended:

 

        this.game.add.tween(player).to({y:55}, 250, Phaser.Easing.Quadratic.Out, true, 0, 100, true);

Is it just me or is it a known bug?

Hmm it's relative to the y coordinate when the tween starts, so the y will constantly be changing in the first instance, where-as it's fixed in the second. It may be a bug specific to yoyo + relative values, but not sure off the top of my head, it may actually be doing what it should do - will have to investigate a bit more. A github issue + reduced code sample would be really helpful.
