Fix API Data Accuracy Bug

My backend server’s API is currently returning the wrong data on several endpoints, even though the calls complete without errors. I need someone to trace the root cause of this malfunction, adjust the logic (or queries) that drive the responses, and prove the fix with clear before-and-after results.

You’ll have direct access to the relevant codebase, logs, and a staging database so you can reproduce the issue safely. Once the patch is in place, I’ll verify that every affected endpoint consistently returns the correct payloads under normal load.

Deliverable: a clean pull request or patch file, accompanied by a short changelog explaining what was wrong and how you resolved it, plus any tests you added or updated to guard against regression.


Example:

In the example in the video I selected to generate a game with 12 numbers from 1 to 12. Everything works fine.

However, when I finish generating the game, the mobile app is adding and repeating numbers that don't make sense.

I need to fix it for it to work correctly.

that's the bug.
