Animation loop

I have a two frame animation as an object and I don't want the animation to loop just play once. When I disable loop my animation doesn't play at all.
If I enable loop than the animation will play

 

Reduce your speed

make it 0.50 to 0.10 or smaller. If it doesn't work, I dunno, maybe it's a bug.

 

Another possible trick is to make multiple copy of your frames.
maybe try 10 to 30 copies per frame.

 

Changing the speed didn't do anything but changing the frames to 30 did. Thanks for your help
