Let's talk about Hunts - a detailed rundown of their assumed mechanics

[KageTokage]

I think the reason those hunts spawn late at times is simply because they're not guaranteed to appear when their condition is fulfilled.

On an unrelated note, I'm thinking there's more to spawning Orghana then I initially thought, as the JP players are claiming to have seen it spawn after finishing a different FATE (Can't recall the name, but the boss is a Manzasiri named Rudra). I've also cleared the More then a Tribute FATE with no spawn, then had it suddenly show up maybe 10-15 minutes later without said FATE being cleared a second time. I'm thinking the spawn may actually require the completion of a multitude of different FATEs, but people simply have a tendency to overlook More then a Tribute for some reason.

In my experience with Orghana, it has seemed pretty unpredictable and random to me. Once I did the fate and had it spawn about 10 seconds later. 2 other times I have done the fate and then had it show up 15-20 mins later with the fate not showing up a second time. There may be some other yet to be discovered condition that also needs to be fulfilled (although that doesn't account for the times it basically spawns immediately after the fate). Either there is something else to it or it could be a totally random time within a certain window.
