the last frame problem

[zhengying]

I found that the animation clip will copy the asesprite first frame as its last frame.
but when I have a transform meta layer, the last frame missing transform meta data.
I think if the last frame is the same as the first, the meta layer must automatic added as first frame.

here is my screenshot:

the result of missing transform meta layer of last frame, I got a weird behaviors , the transform curve not the correctly in the run mode, but seem ok in preview mode.

in preview mode:

editor scene or game scene
