Players are reporting numerous issues since the game’s latest update, most relating to chat. Earlier today, the company acknowledged that it was aware of a bug preventing characters under level 11 from sending messages outside of their parties. The latest message from the community team notes that it is “currently having an issue affecting the chat right now” and that the “team is aware of that and currently working on addressing that problem” — the problem being that the last fix apparently nuked all chat but say, for everyone.
