When you visit a friend or Guild member while the Help chat or the Guild chat or the News chat is active, then, after returning home, the chat automatically jumps to the Global chat... Weird ! This I don't want... Can't remember this behaviour was like this last week....
I have experienced this.....
And when you were in a 'Whisper' session with a friend that you visit, (to know exactly what building your friend wants buffed), then returning home makes the chat jump to the global chat window.. but with the friend's tab still visible, like in the 'Whisper' chat... Clearly a nasty bug here.....
this bug has been known, keep in mind to not type anything when you return from some1 elses island or an adventure, or things might end up in global.
Thank your for the pertinent advise.
The "Update" of may 16, 2012 did still not correct this "Bug" :-(
