Bug in the Sovereign wallet (windows qt version)?
Encrypting the wallet works as expected and leaves the wallet encrypted and locked. Then the PoS message "Minting suspended due to locked wallet" appears as expected, but...
There is no selection in the Settings tab for "Unlock Wallet", so once it's encrypted it remains locked and staking is never possible, it seems. Not expected!
open the console, type (without quotes) "walletpassphrase <password> <seconds to remain open>
optionally add <mint true>"
example: walletpassphrase somefuckingpassword 9999 true
Will leave the wallet locked for anything BUT minting.
