What does Defekt Mean

This word is showing up beside a players name where it says Cheat. What does it mean. Thanks

It is the very bottom one in this picture

Sorry for the late responce. Must have overlooked it.

It means that he is not able to read that player-file cause the version is different to the tool-version.
For example. The playerfile is still from Alpha 4 and you use the current tool that is working with Alpha 5.

Its not bad. As soon as he logs in again, the playerfile will be updated to the new version.

If that happens to all of your player, then check the Version in the config, since you might have it set to an old version.
