Character build code

Beginne mit Classes/PassiveTreeView.lua in Zeile 749 und reproduziere den Absturz mit dem verknüpften pob.in-Build: Ändere einen Ngamahu-Platzhalter zu magic, speichere ihn und öffne Tree. Verfolge den OnFrame-Pfad rund um den nil title-Zugriff; fertig ist es, wenn diese Sequenz den gemeldeten Fehler nicht mehr auslöst.
