Error: https://pastebin.com/raw/fd9UptHw

I'm using catserver, 1.12.2 spigot&forge hybrid.

I'm not using Bungeecord, multiple server instances, etc.
Error is repeating every several minutes.
Started after update from BETA-1 to latest dev build.

modlist: https://endimc.pl/?p=mody
plugins: WE,WG,PEX,Vault,Essentials,ProtocolLib.

Nevermind, this was caused by plugin conflict
