After running with some quite groups in the last days I figured out now that the chat client is broken for me. I could read general chat, advice, trade, guild and tells, but not the party chat. Now most of you will say: "Just set incoming text to "party" again and things should be fixed. Nope, that's is not the problem and switching Party chat on and off, even creating a new chatwindow with incoming text set to "party" didn't fix it.
So if you have run with a Bladeforged Paladin named "Thrakor" in the last days and perhaps even squelched me, I am not that dense - I couldn't read what you typed in the party chat. I can only guess how strange and incoherent my own text messages probably were - good thing I am in the guild "awkward moments"... Like when I asked three times in party chat if the melee monk wants the EE handwarps I pulled and than looted myself because I saw no answer. But perhaps the monk wrote three times: "Yes please" when I asked and "***" when I looted them and logged off..
