Guys,
Sorry guys but unfortunately the mechanics of the easter basket (combined with other things mentioned) were on a timer, drastically reducing the time available to do the quest, to my misunderstanding. I will shoulder the blame for this one, having thought the timer was significantly longer, hence the extended duration of the quest that I posted.
Apologies to those that missed the quest timer, but I plan to make it up with a follow-up event, that will likely involve more riddles , to come in the near future!
