Hi,
Apologies for the delay in getting back to you. Iris does not change any of the guarantees made around the order in which actors are sent/received and when OnReps are called, so I don’t believe there’s any way to ensure the ItemInstance is received and setup before the OnRep on AThrownActor is called.
There have been some changes made recently to better support replicating UObjects as their own root object. I’m currently asking around to gather some more information on those changes.
Thanks,
Alex
