The buggy behaviour of A caused buggy behaviour of B that caused buggy behaviour of C, just so happened to align enough to "look like it is working".

Double fuckup if the thing is backups and your data is gone. Reason why we check not only "does the backup job finished" but also "does the size looks right", because backup with 0 files still returns OK...

Haha yeah, been there. I forget all the details, sadly, but there was some long-present bug with how the frontend architecture word in the dev environment that would keep the changes from being propagated. But every member of the team had set up a workaround so that, on their machine, it would load the correct assets some other, undocumented way, so they wouldn't notice the bug.
