DoN's 3D-Pathfinding / Flying-AI system (with full source!)

Hey, ! First of all thanks you for such awesome plugin! It saved me a lot of time!
But, it looks like I’m run into issue with using plugin in c++. It looks like I cant include “DonNavigationManager.h” anywhere, because it’s have “DonNavigationCommon.h” in include list and that include have “AllowWindowsPlatformTypes.h” include, which does’t not allow you to include it more than one time. Am I right or I’m doing something very wrong? I can make a example project.
