I've been having a problem casting spells as a White Mage since the patch. Sometimes I'll cast a healing spell, and even though it animates, and there's no reason for it to fail; the target's HP doesn't rise.

Other times, I'll get a message that something can't be used right now. Even though the target is well within my range and line of sight.

Also, I've always had to double-tap things like Benediction and SoS to make sure they cast, but I've been having issues recently where no amount of button spamming will make them cast.
