The banner (no pun) when Iron Banner starts tells you it's only for 1 week and when it ends (likewise all the events show an end date/time on their banner). I guess the problem is some people just dismiss it without reading it. Hiding Xur was brought back because so many people cried when it was on the map where he was. They said it was too casual and to be fair this way helps both crowds cos you can go search for him if you want, or just have a service tell you ( I follow a XurBot on twitter and have them on some discords). The reset times don't change, so everyone just knows them. Resets happen at 17:00 GMT daily or weekly on Tuesdays. Whisper of the Worm is on Io from Friday to Monday resets. I don't know that it's new people not picking up motes because this wasn't really an issue when it was beta and new to everyone and these are not low rank people. It's almost like there's a reason for it. Maybe they got shouted at for stealing motes so thought fine, I'll leave them! Only one Primeval spawns. It spawns with 2 Primeval Envoys (Wizards) and a bunch of little Taken. You absolutely, definitely, positively should kill the envoys before firing at the Primeval otherwise you're a bad team-mate and I'll poke you with knives!
