Seems I got the luck others missed out on. In my two cities, I was able to get the full main prize with a couple of extra fields, even before the surprise box. In my diamond farm city, I went for WW shrink kits on two separate days and ended up with 12 new kits. In my main city, I went for the Wheel on the last day it came up and got a total of 11 kits, enough for another full Wheel.
As I always do, I ignored the calendar, never attempting to find a daily gem. I did select the gem shards for the Daily Challenge, then used the shards at the end to grab the most valuable prizes, with help from the "Wiki that shall not be named". More fodder for the AD. I would have ended up with more for the AD selecting the non shard prize in the DC, but the shards are different and allow me to interact with the calendar a bit, so why not?
Surprisingly, in both cities I was able to complete all of the tablets. The first time for this event, the first time in two cities. Prior to this event, I have only ever completed the tablets/books once. In my main world, I got them all the day I went for the Wheel, close to the end of the event. In my WW world, I stumbled across the gold tablet on the last day while using up the last of my tools, with enough time remaining to complete all the tasks. In my main, I stumbled across a second gold tablet on the last day with enough of the other tablets needed to complete the tablet set a second time.
In both cities, I had a handful of tablets leftover, getting them all towards the end of the event, at some point, I was done.
Overall a good event for me. Typical event, typical results.
