Dual Spec can wipe your action bars

Bought Dual Spec for 50 gold in World of Warcraft: Forever? Then you may log in to empty action bars. A bug can wipe one or more bars when you log out. Combat is not affected.

What happens

Not every logout triggers it, and it hits different bars each time. Some players lose one bar, others up to six, and without a fix it adds up until all bars are empty. Players report it on the official forums since 8 November, for every class. Some also lose their bars when they switch spec. Blizzard has not responded yet, and the bug is not on the list of known issues.

What helps

Many players save their bars with an addon and load them again after logging in. Myslot and ActionBarSaver: Reloaded are the two names players mention. Myslot was made to copy your bars to another character or computer, but it works just as well to restore them after the bug.

No addon? Take a screenshot of your bars, so you can rebuild them faster. Which addons work in Forever, and which built-in tools replace them, is in our UI guide.
