Can't reproduce. Need more details. Can you run it with RUST_BACKTRACE=1 in debug build? RUST_BACKTRACE=1 cargo run -- --no-fork from project folder or just make run

@Zardoz89 can you check with d174222d6df5e55887a09c299f91a9b1e7cac046 ? if it still reproduced, can you post backtrace here? 😄

[Zardoz89]

It's fixed! Thanks
