I didn't touch any of the animations or scene code, so it should not have been affected.
However, if something is lagging that you think wasn't before, let me know what scene it is and what platform you're playing on (windows/mac/android/web pc/web android/web iphone).
Also, an hourglass-only path is not planned, since I don't think it's unique enough compared to BE and AE.
But some other paths might have Mia with an hourglass figure.
