I hope that these articles have answered your questions, and assure you that we are fully aware of these issues and are working to resolve them as quickly as possible.
I will now be closing your ticket. As I’m sure you can imagine, we have received a very large number of tickets about these issues, and as such are working to correct everyone’s issues through large-scale fixes as opposed to on an individual basis. Your issue will most likely be corrected automatically in the coming days, so please wait at least 72 hours before submitting another ticket. If you are still experiencing issues in 72 hours, please make your new ticket’s subject as clear as possible.
Thank you so much for your patience as we works towards completely resolving these issues, and in the meantime good luck on the Fields of Justice!
