Triple Bump!
Please add blueprint/network support for all important container types. Arrays are nice and all but… it’s arrays, and they are very limited.
I really figured this would have been a higher priority for epic since container types are fundamental and their use-cases are enormous.

I do recall reading somewhere on answerhub that it can be implemented in custom source and has been by some users but I have yet to find any source showing the implementation. After checking the source it looks like to implement TMap for BP and replication you need to add support for UE4’s serialization and reflection yourself and the replication part should be a snap. It’s the first parts that seem daunting. I wish I could do it myself but my c++ is very limited as the bulk of my experience is in managed languages (c# mainly).
