I’ve got a flash game that gets loaded through a preloader.swf. But something curious started happening with this singleton I was using.

Whenever I change something in this singleton everything is working fine when testing. But as soon as I start movie.swf through preloader.swf the changes I’ve made in the singleton don’t show. Changing code in any other class works fine though.

The only way I can make sure the changes go through is by re-compiling the preloader!

I’m completely clueless about what could be causing this.
