Since the new update macros are stored server side. Well I had adjusted all my macros and updated them for all my toons recently on my main pc. Yesterday I logged in 1 character with my laptop which had old out of date macros. Bliz ended up overwriting my currently stored server side macros with my laptops old ones. Now when I log in with my main home pc it still has all the old macros from my laptop there.

Be warned about logging in. You may delete all your macros!
