Early on, when it wasn't clear how to use these three assets I am pretty sure I might have thrown good money after bad by using one or more of these expansions in attempts to remedy perceived problems I was having. Now that I know how to use them, I'm wondering how much money I just lost , if they were indeed not needed. Are they still available for usage in the future. A bookeeping system would be ideal for keeping track of the Build Augmentation Templates.
