hash: Hash

AboveLookaheadHeightLimit

A downloaded block was a long way ahead of the state chain tip. This error should be very rare during normal operation.

We need to reset the syncer on this error, to allow the verifier and state to catch up, or prevent it following a bad chain.

If we don’t reset the syncer on this error, it will continue downloading blocks from a bad chain, or blocks far ahead of the current state tip.
