We rarely catch things breaking in code reviews, I agree they are really bad at finding bugs. Automated tests and linters are better at finding stuff like that. The things we usually address in code reviews are architecture and code design issues, and occasionally edge and interaction issues that are outside the scope of what might have been considered when implementing.
We also have frequent production deployments that everyone on the team can do, I view that as something that is independent of code review.
