Mobs not showing casting message

[Jigga]

Fought soothsayer and was waiting for him to cast but noticed I wasnt gettin the message but I could see his spell particles. You can see that his spells are getting interupted but the message XXXX begins to cast never showed up. You can see other mobs around me casting.
