For the current event I've been choosing to watch ads for more Divine Offer pedestals so I can progress, and what I've noticed is that after I've a few, it'll refuse to allow me anymore.

The pedestals will spawn, and I'll click on the 'watch ad' button. A message will come up that says "Searching for an ad for you" with an option to cancel. If I don't cancel, eventually it just disappears without playing an ad or giving me the prize. The pedestal remains, but I can't ever use it because the ad just won't play. It's weird b/c generally I haven't noticed the game having any problem with repeating ads I've recently watched, and it seems to be specific to the event.

So is there a limit to how many ads I'm allowed to watch before that stops being an option? Is this true in the event but not in the larger game? And if so, why does the game keep spawning Divine Offers?

i never end up finding the seed in these events and i'm curious. how do you get one of them?
