Hi. Yes. It was a bug on 1.0. I wasn't aware of that bug because I'm testing this addon on an armature. I have fixed it on 2.0 for quite a while. It was on the beta branch. I guess it's time to release it, since I have used it and it seems stable enough.
And sorry for my website, I was just listing my old landing page at that moment because I haven't got my GitHub page set up. I've changed it to my GitHub now instead.

I'll give it a 5 stars for now, even tho I got an error in 5.0 and 5.1 (works in 4.5 for me). I submitted a bug report on GitHub.
The bigger issue however... your listed site is super NSFW. Come on, man! You can get people in very uncomfortable situations :)
