In the SkeletonRenderer.m file object drawNode was never released.
Adding [drawNode release] to dealloc fixed this issue for me.

Hi,

I've created a project with skeleton, which has several animations.
There is a slot that should be visible in some animations but invisible in others.
When I turn on visibility of this slot for one animation the editor automatically turns it on for other animation.
Looks like this issue is related to http://ru.esotericsoftware.com/forum/visibility-problem-issue-4820?p=22687&hilit=visibility#p22687
Help, please.
