old .rtconfig file doesn't work by renaming it to .blend

[wikid24]

An old .rtconfig file doesn't work by renaming it to .blend

I didn't create this .rtconfig file it's old but it's used as a template by FFXIV modders to map MMD (Miku Miku Dance) model animations to FFXIV models.

steps to reproduce:

• open the included blender file in blender (walking rythmically.blend)
• using latest version of RT addon, import the included config MMD Config REDO (rtconfig renamed to blend).blend

Using an older version of RT addon (apparently the version I have from January 2023, also included) works on the .rtconf file

blender version 3.6.5 LTS

included files:

• old version and new version of animation retargeting plugin
• MMD Tools addon (just incase there are any issues loading the blender file, included just in case but probably not needed)
• MMD Config REDO.rtconf
• MMD Config REDO (rtconfig renamed to blend).blend
• walking rythmically.blend - sample blender file before using 'load config' in Animation Retargeting plugin old rtconfig file issue for mwni.zip
