Or, alternatively, someone went on vacation and then came back after they got auto-removed.
And yeah, sure, there are people who don't say anything but I'm always wary about making those kind of judgements without more information. One of the most active and involved Dukes in Arcaea rarely says anything to the realm and only sometimes to any of the message groups because he prefers handling things via PMs either with his knights and lords, the other Dukes and Duchesses, or his King. If he went on vacation, it would probably look like one of those silent Dukes disappearing and coming back, but not to anyone in the know.
