Hey DaxJericho-
It appears that the crash is related to an AddChildActorComponent node being used. Can you provide a screenshot of how your CharacterBase and ChildComponent are setup as well as anywhere the AddChildActorComponent node is used in your CHaracterBase blueprint? Additionally, if you believe the issue arises when using data table / structs, can you try setting each up in a step-by-step fashion where you save and close the project each time. This should help pinpoint what change causes the issue to occur. To help provide more information, could you also provide the full callstack from the crash report window as well as the log files from the crash?
