There are better ways. It’s not exactly efficient to replicate them anyway. TMaps work fine, they just don’t support replication (like the vast majority of other UE containers and types).
Also, don’t swear pls. Forum Rules
Has anyone actually tested this before bleating on about it’s lack of support? I know maps that are created by BP don’t support it, but if you create them in C++ and provide a NetSerialize function for your custom USTRUCT, it may work.
