Hello!

I've read this topic Linked Mesh Bug, but I have quite the same bug, a crash, and another weird behavior.

Here's my process. It's quite simple. My goal is to use several card faces, and only one image card back. So, each card face would be a linked mesh, so I can rotate my card and see the back easily.

So, in the Setup, I have made a basic mesh on my card face. I create a linked mesh, then I rename the new created one into the card back.

1. First bug
Then, I cannot duplicate the bone or else Spine is crashing.

Here's the log:

What I did was I duplicated the slot instead, and it worked. I just had to create another bone, and drag my new copy slot inside. Tricky but it worked.

2. Second bug
Next, I went in the Animate mode, I just made a rotation on the card itself using the mesh. I know I could use scale, but not for what I intend to do in the future. For now I only use my first image, my card face, the '6'. Next step would be to swap image and show the back.

Then the weird behavior happens. I go on frame 5, the middle of my animation. And there, I want to switch my image.
And my animation is ruined because the new display image use its source mesh and replace the actual mesh.

After:

Once again, there's a trick, I just needed to do the image switch on another frame. Like frame 6. It creates a new weird mesh I didn't want, but it's ok, I just need to drag my key from the 5th frame on the 6th to replace it, then I can move all the keys from the 6th to the 5th. If you still follow, cool :p
