Hi. I added the Amytis city schema recently. If I apply a Chronos schema, is the Amytis permanently lost (until I buy it again), is it rather inactive while Chronos is there, and returns when Chronos runs out, or, last possibility, are the bonuses for both schemas effective while Chronos remains active? (Fat chance for the last optioin, right? :D )Once bought, City Schemas won't disappear. You will be able to switch between them anytime :)

Hello Ike!
Don't worry your Amytis city schema won't be lost if you apply Chronos schema. 
After 7 days that Chronos city schema runs out, your Amytis city will be able to be applied again!
Personally I have Poseidon's city schema at the moment as you can see below.
But Hecate (which I had bought in the past) is still there waiting to be applied again when I choose to do so!
So don't worry your current city schema will be safe and sound while Chronos is applied!
Too bad the effects of each city schema are effective while the city schema is active so once you apply Chronos only those bonuses will be active!

I just noticed that even the the CDBs for the standard cities are higher on the FB servers.
Hmm
P.
That Chronos looks cool +2000 CDB.. Is that the the reward of the Chronos Quest I heard in FB server? How can someone get that?Yes, you can receive it for completing a Monthly Quest, or you can buy it in a Special Offer.
