I am running a game with few hundreds player playing. But idk why, some player (not majority) experienced data revert, which their data revert back far before. Normally, it save properly. And they say it caused by server hopping, and i tried but nothing happens.
If the data just reset, i can easily find the problem, but the data revert to the past and not happened to all player, then i cant figure it out.
Do you know why and how can i fix it?
