Increasing amount of non-completable DEs
This is caused by there not being a reset in a couple of days. Without the server resets more and more chances for DEs to bug out happen. The good news is hopefully by letting the game be on its own for a few days the more bugs are reported and the better the development team can iron out all of the bugs without resorting to a server reset every few days.
But I agree the current state of the DEs can be annoying!
Yup. We really could use at least one server reset a day til devs find a way to fix the stuff for good. Currently so many zones are simply unplayable either due to bugged skill challenges that block the map completion progress or bugged DEs that make it a lot harder to level through the zone or play it at all like in case of most of Orr.
