Okay, I created a new quest, added under QuestAliases a PlayerRef, added the PlayerAliasScript, then went back to the original quest, removed the PlayerRef there so it only contains the QuestScript01 under Scripts. Still, as the property QuestScriptProperty01 from PlayerAliasScript I can only select NONE. edit: Someone the old quest was buggy, created a new quest where I attached the QuestScript01 script, and now I can add that quest as the property to the PlayerAliasScript. Am I supposed to set quest as the value of the property QuestScriptProperty01 here? Cause in game the function PlayerLoadedGame isn't executed.
