Can you please provide me the output of "/version" and "/version minepacks"

• Paper version: git-Paper-561
• API version: 1.13.2-R0.1-Snapshot
• 64 Versions Behind

MinePacks version 1.19.2

MarriageMaster and MinePacks worked fine together before updating to the latest.

Thanks for the report. This should fix it: https://ci.pcgamingfreaks.at/job/MarriageMaster/78/artifact/target/MarriageMaster-1.31.15.jar

Apologies for not getting back. It did indeed fix the issue. Much thanks.
