🐞 Problem Description

BetterModel 3.2.0 appears to have an API compatibility issue related to EntityPotionEffectEvent. The exception is triggered when an Armor Stand receives a potion effect. In my test case, the Armor Stand was spawned through MythicMobs, although the error itself appears to originate from BetterModel's event listener.
Error:

java.lang.NoSuchMethodError: 'org.bukkit.entity.LivingEntity org.bukkit.event.entity.EntityPotionEffectEvent.getEntity()'
    at bettermodel-3.2.0-paper.jar//kr.toxicity.model.bukkit.manager.EntityManager$standardListener$1.potion(EntityManager.kt:90)

The potion effect itself is applied correctly and the MythicMobs mechanic continues to function normally. The exception only appears to affect BetterModel's event listener.
Based on the stacktrace, BetterModel may be referencing an outdated EntityPotionEffectEvent#getEntity() API signature, resulting in a NoSuchMethodError at runtime.
