Remember guys

Nah dude, the users are fine, it's the UX designer that's the problem! Always trying to do things that make no sense!

The user is always the most avid tester.
Just write the best code possible.

Dealing with the same issue

No user issued action should cause a program to throw uncaught exceptions or similar. And yes the UX is often a huge problem, too.
But yep there are dump users out there. It is fun and terrifying when you read play store reviews about apps that doesn't serve some users needs but the app never intended to have this functionality. Too bad no example here to show. ^^
