Element dissapearing

[mani.a2...@gmail.com]

Hello,
I have a problem with disappearing element. In the beginning of animation everything is in the right place, but after few seconds one palm tree is disappearing to show up in the end (but not always it is showing up in the end..) of animation. It's the issue with palm tree on right hand side.
When I'm developing, in GWD it looks ok, but after publishing this problems is present.

Would appreciate any help.

Thanks,
Mani

P.S.
Animation doesn't work well in Safari but it's other issue I mentioned on Forum before...
