Failed the achievement Visions of the Sandy Islands

It does not recognize the olmakham bandolier, it does not recognize neither the achievement nor the one that it subsequently makes. Already on Tuesday I gave account of this failure but to date of today it has not been answered on its part a possible solution. In the report 7365044: Achievement Vision I sent captures of said failure, Please at least respond saying that it is being revised, it is not worth continuing with the achievement and the expense in manufacturing the 2nd messenger if it is not going to be able to finish . Waiting for your response, greetings.
