[CockyCat]

systemctl start babylond.service & sudo journalctl -u babylond.service -f --no-hostname -o cat, always show :
panic: validator set is empty after InitGenesis, please ensure at least one validator is initialized with a delegation greater than or equal to the DefaultPowerReduction ({824635291200})

ps:

When i upgraded v0.8.5, and run this:

wget https://github.com/babylonchain/networks/raw/main/bbn-test-3/genesis.tar.bz2
tar -xjf genesis.tar.bz2 && rm genesis.tar.bz2
mv genesis.json ~/.babylond/config/genesis.json
last, I start service and also show this panic:
