On PC-NA, in English, Murkmire Guild Traders are lacking the text for their names and locations on the Guild home page (obtained by pressing G):

This text is also missing in other parts of the Guild UI, such as when you place a bid on a trader:

This bug was present in 4.2.6 (on Sunday) and persists in 4.2.7 (this week). It only exists in the English client as far as I'm aware (e.g.
according to the Tamriel Trade Centre changelog which states that Murkmire Guild Traders have been added to the addon for
non-English clients).
It's a real problem because it's making Guild members anxious about whether or not we have a trader. It is also preventing third-party addons such as TTC from working properly, since as far as they are concerned, the Guild does not have a trader. Not being able to upload the contents of the Guild Store to TTC will greatly reduce our sales.
