Earlier this evening on the PC EU server, I accepted the Mages Guild daily quest and Bolgrul's Undaunted daily quest. The Mages Guild asked me to recover "Big Sister, Little Brother" from the Root Sunder Ruins public dungeon in Grahtwood. Bolgrul asked me to retrieve a molten pearl from the Aldunz delve in the Alik'r Desert.
After I completed them, I turned them in, then went to Shadowfen to do Arx Corinium.
After the daily reset for the PC EU server, I went back to get the next day's Mages Guild daily quest, Bolgrul's Undaunted daily quest, and the new Undaunted pledges.
The Mages Guild asked me to recover... "Big Sister, Little Brother" from Grahtwood.
Bolgrul asked me to... retrieve a molten pearl from the Alik'r Desert.
I'm thinking that perhaps the daily quests are not resetting at the new server reset times, but rather at the old time of 1 AM EST/2 AM EDT. Note that I'm not referring to the ability to accept, complete, and turn in a daily quest, but rather the rotating list of specific daily quests which each quest giver hands out. The Undaunted pledges are obviously being updated as expected, but it seems like some of the other rotating daily quests might not be updating at the new reset time.
I'm also wondering if this might explain some recent comments/complaints from a few forum members about the Alchemy daily writs involving Mudcrab Chitin, in which they claimed to have received the exact same Alchemy writs for two days in a row. In other words, I'm wondering if they accepted and completed a writ after the old 2 AM EDT reset time, then accepted the next day's writ after the new 11 PM EDT reset time but before the 2 AM EDT reset time, and therefore received the exact same writ as the one they got the day before.
If they were on the PC NA server rather than PC EU, it could be the same scenario but just different times-- between the old 2 AM EDT reset and the new 6 AM EDT reset, and then on the following day between the new 6 AM EDT reset and the old 2 AM EDT reset, such that they were on different days using the new reset times, but on the "same" day using the old reset times.
I've fought mudcrabs more fearsome than me!
