Tweens ruining object positioning

I’ve encountered this problem several of times before and have yet to find a solution. I’m quite surprised as it seems like something that would be at least fairly common.

Here’s the issue. Say you have a Sprite, on this sprite you have 2 other sprites positioned precisely. For example, you have a Character Sprite. On this Character Sprite it has 2 children, the base, and the hair. It’s very important that they’re positioned precisely for it to look correctly. Now say for moving the character you have some tweens in place. You tween the character object that contains both the base and the hair sprites. Sometimes, not always but quite frequently, afterwards the two sprites within the character sprite (base and hair) aren’t positioned correctly.

For possible remedies I’ve tried setting the coordinates of the children to themselves (I don’t know, I thought this might make it recalibrate…). I also tried removing the children and re-adding them. No avail.

Anyone ever experience such a problem? This is really going to cause me some problems down the line…
