## AI overview

The article reports that Ethereum's Morden testnet fork for Spurious Dragon encountered a consensus issue between Geth and Parity because Morden-specific nonce rules conflicted with new EVM rules. It says the issue was specific to Morden, with no known Mainnet impact, and announces Ropsten as the replacement testnet.
