All data just deleted

All the data in my game (for everyone) just got deleted. Why is this? It’s not the scripts because it worked just fine yesterday.

is there a mistake in any of the datastore names?

Nope! I’ve checked it. I haven’t touched it since last time i codes and then it worked fine.
It’s most likely a bug in the engine.

Did you have any handlers if an error occured; like a debugging print? If so, what does it say?

plus, it might have been a data store fail/error.

No errors, no nothing! Hasen’t this happened to you before?
