Why do I often mined two blocks in a row? Is this a bug?
I noticed that the list and order of validators does not change, but many other validators also often mined two blocks in a row.
This happens when a validator prior to you didn't process a block so you take it's place, then after that block is your turn, hence the consecutive blocks forged by the same validator.
