The units are actually not meant to be replicated. The action system works by sending actions to each client, and the client executes these on the non-replicated actors. In a turn based game it is not necessary to constantly update the states of actors across all clients. Using the action system eliminates the possibility of laggy updates of movement etc., since anything that is shown to the player is executed client side. Before I dive deep into this, have you made any modifications to the toolkit, or are these issues on a clean project?
