This has been the norm for every one of these events. Some get the rare drop almost instantly, others NEVER get it no matter what. Try to put this issue in the "I Don't Care" box. I have.
Also I think it's time to do away with those fairy chests that you have to chop. Those prizes are just sad.
One more thing (gripe). Please do away with visiting other kingdoms. It just causes havoc for me!
