Hello!
I have this weird behavior with the mesh and visibility keys.
I'm on Spine 3.4.02 pro under Mac.
So I have an image, it's been converted into a mesh. First frame, with one mesh, last frame with the mesh changed. I also added a visible key at the begining, and a invisible key at the end.

Problem is, if I decide to replace my invisible key by a visible one, Spine kills the 2nd mesh key.

I know, this makes 2 visible keys, but hey, my mesh key!
