Edit: It seems like it’s an issue with the Elastic EasingStyle. I was going with “In” “Elastic”, and switched it to “Out” “Elastic” and for some reason it skips the first half of the tween and immediately moves the GUI to the halfway point and continues from there. Since I was using “In” it was doing that in reverse and playing the first half of the animation and then skipping the last half of the animation. Elastic is just broken.

I’m kind of having a big problem with this. That frame is getting clipped off the screen when half of it is still visible. File in conf tags:
