Occasionally inside of T6 tonight my team occasionally came across an issue where spells couldn't be casted on a party member. AOEs like Adlo, Protect, Medica and even direct targets like Cure and Raise were unable to be placed on the player. Not having access to the last two was fight-impacting when the person couldn't be cured due to the error and then subsequently couldn't be raised.

The text that pops up is "Unable to execute action due to aetherial interference."
