One thing i am curious of here is, ServerSetReplicatedTargetData is a reliable RPC, meaning it will be set of instantly (Reliable RPC’s are sent instantly they are called) The only way i can see this being an issue is if it all happened in the same frame (but again that seems odd). And reliable RPC’s are ordered. I have never seen this issue before, but maybe my use cases have ne required sending a ton of TargetData for a single ability activation? We tend to split our stuff into reusable abilities that do the one thing they do.
