Issue placing the accessories of Neptunia characters in Blender.

[RamCPUCandidate]

I am having trouble placing the accessories of characters (like Blanc's hat, Neptune's D-Pad clips, etc) in Blender. I am using an .ism2 addon to Blender (called NepTools) that allows me to import them but stuff like that won't import and just get a very long error (something about trace callback, I can get a screenshot later if needed)

So, help? I have ripped the models myself and this happens with all accessories while characters work completely fine.
