Rift is currently having an issue where ALL communication is impossible, as all chat channels are not working and neither is mail.
I just logged off as I figure that defeats the purpose of a game if you can't communicate. :/
Hopefully it'll be fixed soon.
What are some errors that made it into your games that basically made the game unplayable?
Errors that affect everyone in the game and made you have to log out and wait for a dev to respond? D:
