Importing animations does not work if a metahuman is linked or collections have been renamed

[chiefmasterR]

Blender version 4.5.9
Polyhammer version 0.8.1

Steps to reproduce:

• Import only the metahuman head dna file
• Rename the two created collections (NAME, NAME_lod_0) to any other names
• Place the two created rigs (NAME_face_gui, NAME_head_rig) into any other separate collection
• Create a collection in Scene Collection and place the root metahuman collection inside it
• Mark this newly created collection as an asset, then link it to another .blend file and try importing the animation

You can also leave everything as is without renaming or moving anything and simply link the metahuman collection in another .blend file. This won't cause any errors, but the animation simply won’t work
