Hi,
Just to double check, are these replays being recorded on the client or server? If they’re recorded on the client, are you adding these subobjects to the registered subobjects list on the client as well?
From this knowledge base article:
“While the server will certainly need to maintain these lists, actors/components on clients should also maintain their subobject list locally, particularly for any actors with local authority. This is especially important if a project is recording replays on clients, as actors on a client will temporarily be swapped to a local authority role when recording the actor into a replay. Because of this, any replay recorded actors should maintain their subobject list on the client, regardless of their local NetRole.”
Thanks,
Alex
