I am a bit shocked that they even manage to mess up a event like that..I was able to be online nearly the whole day and only got a message later in the evening that he is there. Honestly I just skipped the cutscence with the bard and gathered every necessary token in this and finished as fast as possible..(and more shocking, the fates were still more fun than Eureka..)

And after that I noticed that you can only put one item in the chest..why?

I am not sure if they wanted to give it the 1.0 feeling but this is really not great for a timed event..
