scale How to keep position of sprite after being scaled(mine keeps moving to left corner)

[gg.wilson]

Hey everyone hopefully this is worded ok and you are having a good day.

I currently have a playable character which can be moved around and collide with objects.

The issue i am having is once it has collided with a certain object i want the players character sprite to increase in size however when i do this using sprite.scale.setTo for some reason the position of the player sprite moves to 0,0. 

Apologise if that was not enough information i can provide more if needed.
