I don't know what happening with my masternode.
it was running for few days and today I can't found it with masternode debug command.
I click Play, it showed error: cannot allocate vin for collateral address.
my wallet is unlocking.
Do I have to recreate my masternode?
Use Coin Control feature (Send - Inputs) to see if 20K stay in the your specified address and in ONE coin pile.
It may get split due to staking - simply send it to the same address again in one transaction.
To prevent split in future you can write "staking=0" in the phantomx.conf file
