Just got a Tempest request, immediately got the item, and when I came back I got the following message:

Oh No! It's been too long since Tempest last called you!

Refreshing the page and clearing cache didn't help.

Came back to where? To the page that the random event takes you to?

I think that error is there because the event can time out, and I think it can time out to stop people who missed the event from being stuck on not getting one again, or something like that. I can't quite put it into words. Maybe one of the staff can explain what I'm trying to say?

Back to the Tempest main page. And I got the item within a minute or so, I don't think time runs out so fast..

If you already got the item then maybe that error happened because of that? I think you can only get one item per event?

Gosh. Know what I did? I bought the item because I thought I have to. And went back to hand it over. Stupid me! Thats what happens when you multitask! :D
