The steps to reproduce crash: class BP_Weapon_Gun_Child is child of class BP_Weapon_Gun which extends class BP_Portable_Basic and class BP_Portable_Basic is child of class Actor. There’s a custom blueprint structure called F_SlotItem where store information of item, and class BP_Portable_Basic use this structure as a member variable. So whenever this structure is adjusted, it will trigger the complilation of these blueprints related. I attempted to create a test sample with a structure similar to this one, but it’s ok, i think the problem maybe casued by class BP_Portable_Basic itself or other blueprints that reference it. But it’s all run well in PIE mode. None of the blueprints related had compilation errors. I don’t know where the problem lies.
