It is possible that #39 also randomly prevents user from changing any values in the editor, here is how to replicate it:
- Make sure no profiles are enabled on your character
- Start editor on your character with some bone edits
- Enter GPose
- Make sure you have
(Any World) armature
- Exit GPose
- Exit editor
- Enter editor again on the same template.
- Bones cannot be edited anymore.
I assume this can also happen iif user has active profiles when entering GPose.
