I was able to trade both CMs but it took the full 30 minutes to do so. The first two times I was able to to trade, the trades were declined. I am positive though that was a result of so much going on at once. Also, some folks also got 30 candies instead of 20 (Congrats to those who did!)
I like that they tried to give the CMS and players interaction, however, I don't think that trade requests were the best method for this kind of event. In the future I would suggest some things like: 1) Make it a "log in at this time" event and they can award a box that grants 20-30 candies 2) Allow us to "trick or treat" the NPCs for candies (each NPC in the castle awards a candy) 3) Even a hide and seek might be fun (give us clues to a location and something in that area (when clicked) will give the candies)
Just some ideas. I'm sad for those that waited the whole time and didn't get any candy. I do hope that in the future it is accessible to all players
@Cuddlewings I haven't completely reviewed the Founders Pack items but so far I noticed that the Chacha Shoulder Accessory is only showing (in red text) as being available for 30 days, but the founders pack description stated that it was permanent.
