We were predicted a single block during this epoch that we missed due to blockchain fork
Unfortunatelly due to the nature of Cardano blockchain it's possible that blockchain forks itself. This is commonly caused by foreign misconfigured pools that run more than 1 block producer node, resulting in forked chain on every block they mint. Or by so-called "slot battles", where different pools are predicted slots too close to each other. Unfortunatelly this is an unsolved problem in Cardano network, that all pools are currently randomly facing.
