I just purchased your toolkit last week and experience using Unreal only a few weeks longer than that maybe. I have a project all setup in SVN source control, and while it may be easier for me to just start a new project to utilize your new version of the toolkit, I find this may be a good exercise to see how upgrading your toolkit in an existing project becomes viable as we go into the future and an inevitable 1.8 gets released with more great features.
So would I go about upgrading my project with the new update. Maybe a better question is how do you use the toolkit in a project: Do you keep the base blueprints in the default folder of AdvanceTurnBaseTileToolkit and create child blueprints of everything placed in the root project folder? A normal programming project would have an asset folder or 3rd party library folder, so in my experience that is what I would expect, but I am unsure the practices of Unreal. It seems some people just basically create their game in the existing blueprints provided by your toolkit, adding more functionality that way.
I guess the simple question boils down to:
Do you have a solution to easily upgrade 1.6->1.7?
