[Pseudochrome]

Date & Time: 5:44 AM EST
Frequency: 2-3 failed attempts
World name: Jenova
Character name: D'neva Vhuh
Class/Level: 20
Party or solo: Party
Steps:
1. Sent in ticket at least an hour prior
2. Received GM message later on in the evening while I was in a new instance while fighting Amemet sync'd
3. Alt+R'd to reply, but every time I submitted my tell, I received an error stating that I was unable to send /tells in Eureka. Attempts were made both level sync'd and unsync'd as well. Eventually I gave up and had to drop from instance.
