Aspt...i believe there is a slash command that can control how many aura's that can appear. It has a max of 40 if i remember and you can bring it to zero by by using the slash command /nui maxaura 0 as in 0 = zero. I hope someone can back me up on this as i am working from memory and havent been online to double check info. But you can do this yourself by entering /nui help and the slash command for the auru's is in the given list...i hope this helps....
