Description

In the testing file: [bone_parents.zip](https://github.com/armory3d/armory/files/2317750/bone_parents.zip)

(1) when enabled layer 1 + 2, the object in layer 2 could be deformed correctly:

(2) when enabled layer 1 + 3, the object parented to bones in layer 3 could be deformed correctly:

Research direction

Start by opening bone_parents.zip and reproducing the three layer combinations described in the issue. Compare the deformation in layers 1+2, 1+3, and 1+2+3, focusing on the bone-parented object's offset when the deforming object is attached. Done means the third combination no longer produces the reported offset while the other two still deform correctly.
