Not sure what is going on; mailboxes have vanished, the stone in the middle of the lake and hoggers’ quest board. None of these are intractable.
Not sure if The Collector and The Westfall Deed is dropping either. It makes levelling a new character weird.
Things I tried? Changing character, disabling and enabling addons. Re-logging. Other people in general seem to have the same problem.
Some layers are broken on each server
I’ve gotten both “The Collector” and “The Westfall Deed” drops over the recent weekend. At the same time, I’m experiencing the other bugs listed. The quest “Find the Lost Guards” doesn’t seem to be working either. I was able to accept the quest but the pile of “remains” isn’t there for either guard. At one time yesterday afternoon, there were about 10 different characters standing by where the first guard’s remains should have been, talking about the issue and what we were trying to get the remains to show. Did similar things as the OP in this thread (e.g. turned off addons, reloaded, dropped and reacquired the quest, etc.) with no luck.
