Creature Spawn event Worldguard

[TenReeez]

I have the following console error:
https://pastebin.com/zRd1tWhd

ME version: R2.3.2
Worldguard: 7.0.6+1cff55f
Paper 1.18.1

I know its an old version of ME, but any newer wont work with Magmaguys ELitemobs atm.

Is the worldguard error fixed on a later version?

Thankyou
