v2.0.5 still import only 1 mesh

[corealt044]

Hello, for some reason for me v2.0.5 still only import 1 mesh. I did change the source code and now it works. but I'm wondering if it's save to do that.
I've modified from this;

    if characterArmature != None or characterArmature.type in ["ARMATURE"]:            
        bpy.data.objects[characterArmature.name][armature_key] = armature_key            
        if len(characterArmature.children) > 0:
            for mesh in characterArmature.children: 
                bpy.data.objects[mesh.name][armature_key] = armature_key

into this;

    if characterArmature != None or characterArmature.type in ["ARMATURE"]:
        for mesh in characterArmature.children: 
            bpy.data.objects[mesh.name][armature_key] = armature_key

Will someone tell me if this is fine and won't cause any problem? I'm new to programming and was changing the code just to make that one feature work.

p/s sorry if I shouldn't be posting here, never use this website before.
