It's theoretically not a bug. This is how the bag was designed by whoever made the item. [...] I was just told that the bag is supposed to last for the entire period of the tombola, which it does, except for few cases where it expires a few hours earlier (not even a day).
Well, of course it is a bug. Descripion of the item clearly tells players that the bag can be used every 24h hours during the event (and that means
whole event). Actually, the bag doesn't fulfill this for the entire event period.
Nothing to see about "item can be used 18 days only". You see, bag is designed to have a bug :p
The event lasted 18 days (+1 extra week on zz) and therefore you could use the bag 18 times with a cooldown of 24 (or 23, can't remember) hours. [...] If anything they could probably add an extra day, so those persons will have the chance to use it again and don't have the item expire before the end of the event.
Well, if an event last longer than 18/19 days (e.g. 21 days as for some events in the past) and bag is designed for 18 days only, the problem and heart loss became bigger and bigger (Beta doesn't matter, I'm talking about the problems coming to live worlds).
I really don't understand why these items aren't designed for 60 days life time to avoid any problems. Even if you can "use" the bag after end of event the event currency doesn't count and has no effect.
I'll suggest that myself, but I don't guarantee it'll actually happen :p
Thank you, keep my fingers crossed. Looking forward the "official" reply.
