NullPointerException after Spigot update

[SlimeDog]

SLM-Spigot 1.2.7 fails to load with Spigot 1.16.5-3070 or greater. Issue confirmed with

• Spigot 1.16.5-3070
• Spigot 1.16.5-3073
• Spigot 1.16.5-3074

SLM-Spigot 1.2.7 works fine with

• Spigot 1.16.5-3069
• Paper 1.65.5-675 (latest build as of this post)

ProtocolLib 4.6.1-b501 ServerListMotdSpigot 1.2.7

No changes to configuration, only Spigot update.

Issue

NullPointerException on server start-up. Caused by interaction with Spigot update. Issue did not occur on Spigot 1.16.5-3069.
