For those who have not yet logged into the game yet with the borked version of Macaroon:

I was able to use the patch for the PTR:

http://www.wowinterface.com/download...uild3.0.8.html

But I had to restore a backed up WTF file (WTF\Account\Account Name\Server\Character\Saved VAriables\Macaroon.*) to get my bars back...seems if you log out it will wipe them all from the LUA and you have to start from scratch.

So, it looks like you won't lose any of your macros as long as you update the addon with the 3rd party fixit patch FIRST, then log in SECOND. The reports are that the update in the official Macaroon addon thread does NOT work, but just make sure to make a copy of your WTF folder and you may still be able to load your bars from the saved profiles after using the 3rd party fix.


EDIT: Also in the comments...
The sky is not falling. It's been updated today in time for the 3.0.8 patch on live.

EDIT: BTW, thanks Maul!

Edit: This version isn't working for me, but the fix that had been linked earlier is ( http://www.wowinterface.com/forums/s...ad.php?t=18454 ).

NOTE: I had to go back to an archived version of my preferences in the WTF folder for the toon I'd logged in with using this update (no bars showed even after applying the patch linked above) so use with caution
