Empirically, I found out that if you set onlineMode: false, the commands on behalf of the player stop working and on attempts they will be used writes Error occurred while executing command: null

[confuser]

@LeonusDH struggling to reproduce this issue. Can you provide steps to reproduce, i.e. what commands you're running which triggers this problem?

[LeonusDH]

@confuser /ban and /mute
