Replacing datasets may a cause of report disappearing?

[pich]

Hi

I've re-published my report and dataset which modified by only add a new measure and edit some formula of the existing measure from PoewrBI desktop to the cloud. The next day after replacing the old one in the cloud (I did not delete anything. Only add one more measure and edit another one), my co-worker told me all of the reports that used the same dataset were disappeared. All of the replacing datasets have exactly the same as before. Only just add one more measure.

Can anyone please explain what's going on about this?

Thank you in advance for your answer
