Avzomend can't be rescaled, with scale to eyes is set to true target height is detected as negative #18

This is unrelated to my previous issue. Rindo model that I use can be scaled completely fine (although it requires manual bone mapping). Model that I am trying to adjust is Avzomend: https://yorshkasencho.booth.pm/items/4118550 I can't really tell what might be causing issues by looking at armature, I even did some manual adjustments to the rig, since by default it has several issues. Bones have been mapped manually.

Turns out I was using older version of IMScale (0.3.0). Issue originally is caused because of both meshes and armature having unapplied rotations and scale. Version 0.3.1 and onwards are not affected by this issue.
