Just be serene Yisak 😎. This is big overfitting. I'm afraid that shake up will be mad. It seems that the public LB does not include Cholera cases, yet they were Cholera outbreaks in Tanzania in 2023 as reported by the WHO. So Shake up will be painful. I hope not to shake as it was for Africa Credit Challenge.

I don't think the area is same though. Did you manage to de-anonimize the transformed latitude and longitude. Those seem like a simple add and subtract.
