Dev: Hay dude , look this page is broken, how long has it been like this.
Me: No? 🤔, Weren't you working on the Database for this yesterday?
Dev: I didn't change anything yet...
Me: Okay, let's do a git bisect and see where this came from.
...After going back in history and checking out like 3 commits.
Dev: It's fine I'll just search for it
Me: 😕, that's what we are doing the bisect for?
Dev: But we've already looked at so many!?
...After some time of convincing, finds good commit, does the bisect and finds offending piece of code. The database details changed.
Me: okay so while it's still pointing to the old database it's working but switch it to the latest one and it breaks. You sure you didn't change anything?
Dev: I didn't do anything.
Me: okay well it seems to me like it must be a database issue, let me know what you find.
10min later...
Dev: Hay dude, soo I found it, I accidentally renamed a table
In my mind: 😲😲😲

I hate working at a company with bad practices like saving database config into git and not making a copy of the database when you intend to work on it, and not edit the f'ing live instance! Not even close to the luxury of migrations.
