Tonight, Jan 5th, zoned to the neighborhood guildhall and lost my chat channels. These are not server wide but my regular autojoin channels. Zoned to the lobby and got them back. Joined the raid channels and wait list channel then after zoning to the guildhall again, they went away. Did this 3 times. I have also been losing them after spending time in a zone. It's been this way since the chat channel maintenance 4? months ago.
