Steps to reproduce [If Applicable]

Unknown. New server. Started up. Shut down, added a mod, restarted, got this.

[cryptiklemur]

Looks like it was an issue with essentials

[JorVaCoding]

It looks like essentials has an addition that allows certain crafting recipes to not be allowed by players (ex: stop players without admin from making tnt), And since the way we determine log -> plank recipes using a null player in a fake crafting table, essentials throws an error because null player doesn't have permissions.

[JorVaCoding]

This might be fixed later, but right now it's not a priority considering we have bugs that crash the world just from players leaving the table.
