Just 1 insignifficant question, do you have your wallet running 24/7 ? I believe not, becuse you got 1 stake now - so you can stake. Wallet needs to be online so your coins can compete on network to be staked!
Could happen I forgot to launch the wallet after restarting the computer i.e. after kernel update.
It is also overclocked and could have crashed when I was sleeping and be offline for a while.
Basically my machine is running all the time and I try to keep wallet always online.
Some rare exceptions can happen.
