Unable to cast aura on others

Attempting to cast a level 5 aura on someone results in a "You don't have a high enough level in that aura to cast on others yet" error. Silkcom said a few days ago that this was a bug introduced with some unannounced fixes during a server reboot and will be fixed in the next update. Recording it here in case anyone has the same problem, and also as a reminder to fix it.

NeoAnderson's existing bug report appears different since it's older and a refresh fixed it for him.
