I have been making a mod (for my own personal use and not for distribution) that places extra merchants on the streets of the market district. I have used some items from Korana's Millstone Farm mod. For some reason I am getting graphics errors in the market district now. They are in the form of long, flat, coloured lines that have come from NPCs and containers. They start at a point and get wider. I have also had problems with the tails of beast race NPCs that I have made. My first attempt (a male Khajiit) had no tail, just a long thin line that stuck out sideways from where it should be. After trying to find out what was wrong and failing, I deleted him and replaced him with a female Argonian. She has no tail, but until I did some tests this morning there were no graphics errors from her either. Can anyone suggest what I might be doing wrong or how to fix it?
Thanks.

You need to use the beast skeleton if you make a 'NEW' argoinian or kajiit.

Its easier to just make a copy of an existing argonian or kajiit and make your changes to that. Everything is already setup for your beast race if you do it this way.

Thanks for the advice, I'll have a fiddle around.
