The plugin may not be loading soon enough. The Type should be "Runtime", and LoadingPhase should be PreDefault. As this plugin is a runtime plugin, and it's needed before the game modules, hence PreDefault.
If a project is packaged with a plugin that contains a custom struct and a function that takes that struct as a parameter, the game will crash when the executable is run.
The game crashes with the following message: [2015.09.09-17.28.47:349][ 0]LogProperty:Error: Struct type unknown for property 'StructProperty /Game/FirstPerson/NewBlueprint.NewBlueprint_C:ExecuteUbergraph_NewBlueprint.CallFunc_GetVariable_ExtVariable'; perhaps the USTRUCT() was renamed or deleted?.
The game launches.
