HI.
I'm having a problem loading an animation into my custom game engine.
When I try to get the attachment under a skin placeholder, which is under a slot, it returns null.
The animation loading process is as follows:

- Getting the draw order from the spine::Skeleton (Line 195)
- An iteration over the draw order to get slots, then an attachment from each slot. (Line 197 ~ 202)
If the attachment is under the skin placeholder, however, its parent slot returns null when I call slot->getAttachment(), so I can't initialize the meshes using the attachments under the skin placeholder.
The following image shows Leg_LEFT and Foot_LEFT attachments under the skin placeholders which is under the Leg_LEFT_SH and Foot_LEFT_SH slots

The current rendered result is as follows:

The character's left leg, foot, and eyes were completely omitted from the rendered result.
These are the spots that were under the skin placeholders.
Could you give any suggestions to fix this?
If you need more information regarding the problem, please let me know.
Thanks in advance!
