Re: [ANN][GALI][AIRDROP/BOUNTIES] - MN/PoS/zPoS Hybrid - Dynamic Zerocoin Staking
Wallet has been killed, sometimes windows updates do it when rebooting the system and doesn't wait for graceful shutdown to complete. Please restore the wallet.dat from a backup in backups/ folder.
Thank a lot, it seems to help 
Next wallet update will include some stability fixes as well to mitigate this.
