LagMonitor not working on Mohist 1.12.2

[lightningo7]

When loading the plugin using Mohist 1.12.2 the below error occurs, I recognize you may not want to provide any support for a sketchy spigot offshoot but appreciate any assistance.

This seems to be bug in Mohist. It's a standard Bukkit feature. Nothing really special.
