Getting this issue in 4.23.1. I integrated this project Mission Component in Blueprints - UE Marketplace into my own and am not able to build with nativization enabled. Strangly enough, this is apparently being caused by a child of the interface class:
UATHelper: Packaging (Windows (64-bit)): K:/UE4 Projects/—/Intermediate/Plugins/NativizedAssets/Windows/Game/Source/NativizedAssets/Public/BP_CharacterBP__pf386912290.h(729) : Error: Unrecognized type ‘IBPI_EventInterface_C’ (in expression TScriptInterface) - type must be a UCLASS
Im very new to nativization, but I’m packaging with exclusive nativization enabled but not enabling nativization on any of my blueprints.
