Relic Castle

So I tried leveling up a Pokemon and when it reaches the level needed to evolve, I got this error. This happens when either leveling up normally or using Rare Candy.
This one seems EBS exclusive.


[Pokémon Essentials version 17]
Exception: ArgumentError
Message: wrong number of arguments(3 for 2)

PItem_Items:317:in `pbChangeLevel'
PItem_ItemEffects:818

EventHandlers:150:in `trigger'

Anyway to fix it?
