Re: (Nutaku) Hellfire Girls
So basically you are saying that Gold tickets are tied to a particular event. But event boxes stay indefinitely after the event is finished (that is, until I spend tickets I earned for a particular event box). So right now if I haven't spent gold tickets from last event (madame Ruri Saijo) I could still use them on last event box?
Just for reference, we are not talking about "free gacha", but about a timed event "event box".
No to everything you said. It's a timed gacha and the time is up for ruri saijo. If for some reason her event comes back and you can use your event-ticket at that point, that'd be neat in some way or another. But right now? No. I think even the ticket colors are different between the last events.
On a different aspect, I've not had a gold ticket (free gacha) expire on me in any way. But, I never saved one for more than a few days. Any gold ticket obtained from any of these kinds of events have no indication of expiring at any point or any ties or significance to where they were obtained. It should not matter where you got them, how you got them, when you got them, and nor should it matter when you spend them.
I hope that helps.
