Component

Anvil

Have you ensured that all of these are up to date?

• Foundry
• Foundryup

What version of Foundry are you on?

forge 0.2.0 (fe2acca 2024-07-22T00:23:01.187259000Z)

What command(s) is the bug in?

anvil --fork-url https://mainnet.infura.io/v3/$WEB3_INFURA_PROJECT_ID --chain-id 31337 --dump-state state.json --load-state state.json

Operating System

None

Describe the bug

When forking from mainnet and attempting to load previous state, the previous state isn't loaded successfully. From the command above you can see that anvil is instructed to dump the state which it does successfully and the previous state is available when the new instance of anvil begins. But seemingly due to the use of --fork-url the previous state isn't properly loaded

--fork-url and --load-state are not supposed to work together, will add a CLI flag to make sure conflicting flags are communicated to user

okay, thanks for the update. To confirm, this means its not possible to use a fork's data (e.g. DEX contracts with liquidity) while also loading in data from recent user sessions to simulate the over time use of our smart contracts locally?
