In 1.16.5 MythicMobs v4.14.1, "PreventSunburn" in "Mob Options" does not work.
Summary
In Spigot 1.16.5 and MythicMobs v4.14.1, "PreventSunburn" in "Mob Options" did not work. The other options do work.
Steps to reproduce
A yml file containing the following description. Everything else is in its default state.
no_burn_mob:
Type: zombie
Options:
PreventSunburn: true
Current behavior
If a Mob has "PreventSunburn" set to True, it will not be able.
Intended correct behavior
Mobs with "PreventSunburn" set to "True" will not burn.

Proposed fixes
I think it works with 1.17 or later.
