I have a UI named CharacterSelect which keeps button classes named interactable base. Whenever I relaunch my editor, CharacterSelect is already marked dirty for some reason, and all buttons internal to CharacterSelect print out an error marked as;
LogProperty: Warning: Serialized Class /Script/CoreUObject.LinkerPlaceholderExportObject for a property of WidgetBlueprintGeneratedClass /Game/UI/Blueprints/Widgets/MUGWUI/WBP_InteractableBase.WBP_InteractableBase_C. Reference will be nullptred.
Property = ObjectProperty /Game/UI/Blueprints/SWidgetNavigator.SWidgetNavigator:DownWidget_10_84DAA9FC455C685228133CBFFD6E0B30
Item = LinkerPlaceholderExportObject /Game/UI/Blueprints/Widgets/CharacterSelect/WBP_PlayerCharSelectStrip.PLACEHOLDER-INST_of_WBP_SpecificUserVersatileButton_C_10
It randomly started doing this after I once added a call to the game mode in the interactable base, but even after I removed it, it continued.
I’ve re-initialized the project, reloaded the save, and even tried zipping the project and opening it there, but the error persists.
