Environment

• Minecraft version: 1.19
• Minekea version: minekea-fabric-1.19-3.3.1
• OS: Windows 10 Pro (but also on other systems since this is happening on a public server)

Thanks for reporting this! I had a feeling I knew what happened, so it was fortunately an easy fix. I just uploaded version 3.3.2 to CurseForge, so it should be available shortly (usually only a few minutes).
