This is the third time I haven’t received crests from the Going Postal housing quest weekly.
When I pick up the quest in Silvermoon, it says I can choose from different types of crests.
When I complete it and try to turn it in at Founder’s Point, all that is available is a default Voidlight Marl reward and some coupons.
The same happened to me today, after the launch of 12.1.
When picking up the quest, it showed that I can chose my reward ; however, when turning it in at Founder’s point, it only showed the marl. A friend of mine in the same neighbourhood (and in my party) was able to chose between the items “advertised” on quest pick up.
