Theoretically, it is normal for bugs to appear in the beta version of the game, and finding bugs is the main goal of testing. But there are some bugs that will make players feel very angry even if they appear in the beta version.

A player suddenly prompted to disconnect from the server while playing Diablo 4, and when trying to log in again, he found that all the characters on his account had been deleted.

This reminds people of the infamous "ERROR 37" when Diablo 3 was launched. Fortunately, this is just a beta version, and manufacturers still have a lot of time to locate vulnerabilities and fix bugs. But for players who are playing, save is save, and it is still very uncomfortable that the characters they have worked hard to disappear out of thin air.

And there is no fix for this error at present, so players can only pray that they will not suddenly drop during the exploration process.
