Describe the bug

I enabled the call_override flag in the [invariant] section, and got this error:

The application panicked (crashed).
Message:  to have same size as the number of (unsafe) external calls of the sequence.
Location: evm/src/fuzz/invariant/call_override.rs:70

This is a bug. Consider reporting it at https://github.com/foundry-rs/foundry

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.
[1]    44947 abort      forge t --mt invariant_

Unfortunately, I cannot link to my project, since it's in a private repository. But I do have many calls to external contracts.

Getting a different error but that is also solely caused by flipping the call_override option to true:

The application panicked (crashed).
Message:  called `Option::unwrap()` on a `None` value
Location: evm/src/fuzz/strategies/invariants.rs:36

To reproduce just clone this repo change call_override in foundry.toml to true and run forge test
