Cache Retime + Animated objects + tyflow _ Issue

[chriss3d]

Hello

I have simple  growing plant setup. 

Animated (manually)  trunk (spline+ animated tySplineMesher)  and animated leaf geo attached to tySplineMesher  geo (leaf animation is baked  via max Point Cache  - 4 samples per frame). 

All works fine simulates and caches. 

The problem starts when I try to retime tyCache .
 
I noticed that animated tySplineMesher retimes just fine and smooth (4x slow down) but the animated leaves are  not. 
The leaves jitters like there is no enough samples being baked into tyCache from the geo. I did check "smooth subframe interpolation" under Shape op but no difference.

Please check the video.

Any clue ?

Thank You,

Best
Chris
