AFKing through hot time

This is probably a silly question, but are there any repercussions to afk through Hot Time and then come back like 3-4 hours later? If I remember correctly, theres a message that you have to click 'ok' for before you get your Hot Time reward. Wouldn't that disappear if you happened to DC before you accept the reward?

You don't have to click anything.
A message pops up saying "you have recieved the box" or something and the box appears in your inventory simultaneously.
The box expires at midnight, so open before then.

I've AFK'ed through ALL of the previous hot times. Never had a problem getting the prizes hours later.

I'm doing that (since it's at stupid AM for me) & just hoping I don't DC :|
