The master branch is currently based on an arbitrary unstable commit from upstream master in Decemeber. Can you please try to reproduce using one of the stable releases https://github.com/flashbots/mev-geth/releases, or you can use the mev release branch https://github.com/flashbots/mev-geth/tree/release/v1.9.25

Answer 2 · 2021-02-26T18:48:59.000Z

I've force pushed master back to be based on top of the stable v1.9.25 release. Thanks for reporting this, and feel free to re-open if you're still seeing issues.
