Timeline animation missing item when replay

I made a timeline animation and set a button to replay. First time it plays well. But when replay some sprite just disappear. Does any one knows how to fix it?

Check where the pivot point "0" is on each frame, that's where the frame is centered.

Thanks for your reply.

I'm working with opacity animation now. I think the problem is because of the opacity value on sprite properties panel and the keyframe "opacity value" are out of sync.(If click on the keyframe dot, the properties panel will show the keyframe properties)

When sprite opacity is 0%, the keyframe opacity suppose to be 0% too but it become -100%.

I'd tried to rebuild but no luck. And it's only some of my sprite opacity animation not working so I have no idea how to fix it. Or if it's a software bug? Anyone knows how to fix it?

I don't understand anything, post the ".c3p" file and tell us what animation you're having problems with and we'll help you out.
