It has happened to me before on a different toon, but never this obvious.
I started playing a prot war, made some macros last night, and put them on the action bar. This morning, those slots were empty and the macros don’t even exist (or saved)??? We are talking about 6 macros, all gone. So i made them again this morning and they are still there. However, some of these macros get replaced by other spells…
I don’t know what triggers this to happen, for example ignore pain macro disappeared and replaced with taunt when i zoned into a dungeon. Thunderous roar spell (not macro) disappeared and was replaced with Execute.
I also have 2x Heroic Throws on my bar so I guess a spell was replaced but I’m not sure what was there.
