I had the ptr version of zul'aman installed and I think WAU just wouldn't update it or install the new version overtop of it. I took the old folder out of the addons directory and updated bigwigs with externals and it pulled the new one off the server. thanks :)
so where do I download all these updated features? Wowace updater doesn't see the Zul'Aman addon as installed so I can't update it that way. It's also not browsable from the main addon listing on the website, at least, if it's not in alphabetical order.
