End of the Calendar

The calendar ends today, and I hope everyone managed to log on each day to get your gold tower reward.
I picked up mine today and placed it in sector 5 up between some of the stone deposits. It's a reasonable shaped piece of land for it, and not much else could fit there, and there's even space in there between the storehouse and the tower to fit my stone mason.

For day 24, I went with the Watermill. Watermill's and Silo's are both nice and useful, but at the end of the day the Watermill is the more costly item, so probably best off going with it for your freebie.

This late in the event, I hope you've all managed to get everything you wanted with your presents, and if you have spares I'm liking the idea of stocking up on 'Return to the Bandit Nest' adventures for 95 presents.

So far, I have 18 in the star, and have completed 1 other one to check it out.
Troop losses aren't too bad, and to date it's the only adventure that will give science books in loot. I'm quite a fan of science'ing up my specialists (probably not all that surprising to you), so this seems like a great way to increase your book supply.
From the initial time I did it, I didn't get any books, here's my loot:

But 900 granite and 2 chocolate bunnies aren't bad.

Here's some other example loot piles others have received.

Loot spots 4 and 5 can have either a bunny, a bookbinding glue, or 2 of one of the types of books in them. You could have the same book in both slots, and potentially getting 4 codex's from the adventure seems pretty amazing (however unlikely).

Info over from test server is that the adventures for presents will be becoming follow up adventures for their similar named counterparts, which will end up keeping them somewhat rare, as Secluded Adventures and Bandit Nest aren't really run all that often.

Stocking up now seems like a good way to go if you can manage a present surplus.
