So they've set up the Urgent Quest calendar to be similar to JPs, seen here: https://pso2.com/news/calendar
Notable is for the first time, we have a 14 hour block of no UQs after 1 week -- directly in the spot where a maintenance would normally happen.
Whether this is to solve issues they couldn't fix in the extended maintenance, or if it's going to be a regular thing, I have no idea. It would make sense if it was to become the norm, as it would make rolling out Ultra Hard difficulties to Urgent Quests easier and less messy. It also gives them the chance to fix things such as the missing Schvelle unit exchange, weapons in Unique Weapon Badge shop missing their elements, and more much faster....
Just wanted to give a heads up so people are aware! I could be wrong on this, but it seems strange that there's that empty block of urgents.
