[10.06 22:45:49] [Multicraft] axieum ran command: reload

Steps/models to reproduce

Run /reload, and there is a high chance that it tries to set a Discord status update with a blank name.

Version

v2.0.1+1.20

Agreements

• [X] I am running the latest version of the mod.
• [X] My version of Minecraft is supported.
• [X] I have searched for and ensured there isn't already an open issue regarding this.

Other

No response

I cannot reliably reproduce this one - it is most likely a race condition between the /reload thread and the timer task thread accessing the config.
