Please run your launcher to obtain the following updates:
Fixed the issue with friend/guild member login/logout messages not respecting System filter settings - they will now only appear in chat windows with the System filter toggled on.
Class coloured names have returned to the chat windows.
Note: I am aware that the new chat emoticons are too small. I will mostly likely replace them with standard emoticons that are easier to recognise at small sizes as I do not wish to enlarge them - it makes the chat look ugly having big fat rows with giant emoticons.
Corrected the party interface lock icon.
The /unstuck command can no longer be used in battlefields due to players abusing it. I will reenable it when I have fixed the underlying issue. /unstuck should cause you to drop the flag but apparently it is not working.
