I have about 6.8k CBX (in 4 chunks) in my wallet. I didn't mine any PoSP block since 1st January. Tell me please what I do wrong?
Wallet (2.1.1) is unlocked, 14 connections, block height is matching with block explorer.
Maybe I should divide my coins to more chunks?
Although you have the funds separated to 4 addresses, I am willing to bet if you check the Bullion Control feature, you will see you have a number of sub addresses that have been created through your previous PoS staking and splitting - before PoSP. I would suggest creating 7 addresses and dividing your coins among them. You will start getting PoSP 1 hour after that and will be good to go.
Enjoy!
Yes, staking is working now after I do these manipulations. Thanks!

Great news! Now keep in mind that each time you have a portion of your CBX stake, that portion will get divided into 2 addresses. This division will continue so after a period of time you may want to consider re-consolidation like you just did to clean things up.
We will implement some settings in the code soon that will combine inputs when under a certain number (500 CBX) so if one has a number of small inputs, they will be autoconsolidated. And another setting to deactivate the autosplitting function for any value under 1000 CBX.
Make sure you stop in and say hi in IRC, we have a community building there. Presently giveaways, bug talk and staking discussions, but as this community develops, we envision CBX beneficial projects to materialize from that meeting/discussion place.
