Could not process block, provided block root does not have block saved in the db

[terencechain]

Since in initial syncing, state summaries are saved in batch at finalized check point or some predefined intervals. If a node restarts with a hot DB during epoch 0, it will not be able to satisfy this condition: https://github.com/prysmaticlabs/prysm/blob/master/beacon-chain/blockchain/process_block_helpers.go#L70

Hence the error:
[2020-04-17 09:41:50] ERROR sync: Could not process block from slot 10: could not process block: provided block root does not have block saved in the db
