Won't gotoAndPlay('start');

I have an animation which is about 260 frames long, which I want to loop continously.

I have a little preloader on the first frame, and the second frame has a framelabel called ‘start’.

On the last frame, I have a basic gotoAndPlay(‘start’);

It will go to the second frame, but after playing maybe a second or two, it will skip right to the end, where I have a framelabel called ‘close’, and will just repeat itself. The first few second, skip to the end. The first few second, skip to the end. The first few second, skip to the end.

What’s going wrong?? It’s such a basic thing that just won’t work.
