I haven’t played much since the patch launched so I don’t know if this started last week or today, but today I noticed that I am seeing loot messages in my main chat window again even though I have the setting turned off. If I go into the window’s Other options, I can clearly see that Item Loot is unchecked; toggling the option on and back off resolves the issue temporarily but it is broken again on my next login.
EDIT: Currency setting also seems to be ignored until toggled.
