Being able to respond to a GM when they send me a tell while I'm in a duty has been hit and miss. I know I'm doing my part correctly (although how arcane it is certainly leaves room for developmental improvement, but we digress). Sometimes it works; sometimes it doesn't. So either it's a nuance of circumstance (like timing of entering/exiting duties and submitting the ticket) or inconsistency in some part of the GM's workflow. I can always receive the tells from the GM, but I get error messages trying to reply. So they try to tell me how to reply and then decide I must be busy/AFK/whatever.

As for specific error messages, when I try /tell gm name@balmung it tells me I can't do tells by typing while in a duty. And if I try /reply it tells me the recipient is not in the same duty. And if I click the name and try to send a tell that way, it also presents an error.

So I don't know if this is a bug or a GM training thing. But I'm guessing it's the latter, so I'm posting here.
