I have two hunters, one tried nui6 and then came back to nui5 because I miss the "bubble"; I can't play without it because I always take a look to bubble to see my and enemy hp/mana etc.
so, I disabled nui6 and got back nui5 but I had a problem: the feed pet frame doesn't let me see the feed icon; I deleted all nui.lua from the char folder in my "wtf" folder, started *only* with nui5 enabled but I always have the some problem
the other hunter that didn't try nui6 don't have the problem, here is a screenshot:
