There are countless threads over the years about activateable AA buttons being greyed out, appearing as if they're already burnt, but if you click them, they function. LotD, Divine Rez, etc. It's the time of day timing out / desynching. Your computer uses a web link to synch time. If the web you use and the web EQ serverside are desynched, this happens. In Windows it's in Control Panel (not Settings) See here: https://www.windowscentral.com/how-manage-time-servers-windows-10 I reset where my PC sourced it's time and never had this issue again. This issue also sometimes (rarely) occurs if a character has been logged in more than 24 hours.
