Lightning effect doesn't work with localized=true

Summary

The lightning effect isn't working while the localized attribute is set to true.

Steps to reproduce

1. Create a local paper server with just mythicmobs
2. Create a new mob with just the Type: attribute defined and add - effect:lightning{localized=true} @self ~onSpawn to his skills. Here's the mob I used: https://pastebin.com/itRcVFyk
3. Spawn the mob using /mm m s issue

Current behavior

The mob executes the skill but doesn't strike a fake lightning bolt even tho I'm within the radius for audability/visbility of the effect. [Legacy attachment omitted]

Intended correct behavior

The mob should strike a fake lightning bolt visible only to the players withing the localized radius.
