Hi guys,
After some careful investigation of these achievements, we believe there are a few technical restrictions and communication issues that are causing the problems here.
First, Molten and Pirate events do not grant achievement credit. This means that if you hop into an invasion right as scarlet spawns, or if you spend an entire invasion on pirate and/or molten events, you will not get achievement credit for that map.
Second, disconnecting during an invasion seems to have some odd effects on participation credit, especially if you end up switching maps in the process (i.e. moving to a different overflow). You should still get credit if you participate in at least one watchwork event after reconnecting, but if you disconnect, you should assume your participation credit up to that point has been lost. This is far from ideal, but it would be a code-level fix, and we wouldn’t be able to get it in before the end of the event.
Lastly, because the previous two issues are not super obvious, people may be losing track of which maps they have already gotten credit for. The meta rewards are always given as long as you’re on the map when it ends. Many players expect this to mean that they also received achievement credit (which ideally should be a reasonable assumption). However, as this is not always the case, they may mark off a map as complete, even though they did not receive achievement credit.
So in order to receive achievement credit, you need to participate and complete at least one watchwork portal event, and still be on the map when the meta ends. It doesn’t matter how far the meta gets progressed, and you don’t need to participate in any Molten/Pirate events.
Hopefully this clarifies some things for you, and many apologies for any frustration this has caused. In the future, we will try to ensure that large-scale achievements like this are more easily trackable to cut down on any potential confusion."
Viene a decir que si entras al mapa cuando ya ha salido scarlet o si solo pegas a filoetéreos y alianza fundida y no pegas a ningún minion de scarlet, no te cuenta el mapa.
Si cambias de exceso (ya sea por voluntad propia o por caida) todo lo que hayas hecho hasta entonces en ese mapa se pierde. Pero si matas a algún minion una vez cambiado, el mapa te cuenta. El problema es si te tira el juego y te vas a un exceso sin eventos.
Así que, como resumen, para que cuente el mapa hay que completar un evento de los de espadas cruzadas y estar en ese mapa cuando acabe todo.
