when I had change the slot's name "right_upper_arm" to "right_lower_arm"
it does not applied into exported json data.
this is not the usual case. i think.
i've been done some testing on slot name change.
i think this bug occurs when
- make slot
- get slot duplicated
- rename the duplicated slot
- export data -> this data is infected
maybe not... if so please fix the bug plz. 🙁
