I was looking for some other quest items when the wayshrine at the Writhing Wall Event crafting location "discovered." I thought that was October 13! But I rode up and, yes, the initial quest (which I'd played before on PTS) was available. I ran it all the way up to collecting vitrified souls and came back to speak to Skordo, but Skordo will not advance the quest. That's when I noticed that the discovered wayshrine is not actually indicated on my map.

Maybe someone should shut that off? I'll tuck the vitrified souls I have in a fridge until October 13...
