Blender4.X-UPBGE_mmd-uuunyaa-tools_ERROR&FIX

[AkagiVoid]

Hi, I'm using Blender's Game engine 4.1. :3
After doing the tutorial to the T, it still gave meh an error. X3
Before activating it:

After attempt to activate it:

(Updated)
So I officially fixed dat by doing dis:

Renaming ""BoneGroup" to "BoneCollections" and "bone_groups" to "bone_collections", seem to have fixed the problem.

And TADA, just remember dat "mmd_tools" haz 2 be enabled first, save preferences, quit blender, launch blender again, open preferences again, add-ons section, search ""mmd", then enable "mmd_uuunyaa_tools", then save preferences, quite blender again, and now open blender again and U should be all set to go. :3
(U don't actually have to restart blender, although it's good practice to do so, dat way no conflicts will happen. ^w^
I even restart my computer after every update or GPU driver installation. X3 )

I hope that helps a few people out. X3

I now understand the issue for 4.X blender. X3
If anyone else is interested, then go to:
https://wiki.blender.org/wiki/Reference/Release_Notes/4.0/Animation_Rigging/Bone_Collections_%26_Colors:_Upgrading

Go into the armatures.py, edit Line 333 "BoneGroup" to "BoneCollections", Line 334&334 "bone_groups" to "bone_collections", then save the py, try to re-enable the plugin, and now it should work properly again. :3
