I reported a bug, a GM told me to delete my WTF, Cache and Interface folders. I wasn't using any action bar altering addons before, and now I'm using no addons at all. This bug is still persistent and the only way to bring my stealthbar back upon stealthing is to completely shutdown and restart WoW. Reloading UI does not work.
Most times my stealthbar will work before entering an arena or RBG, then all of a suddon I use ShD or vanish and my bar 1 remains... This is quite annoying.
I've only had this problem since 5.2
