Two Problems…
Problem #1
Units all try and jam together into the same spot and I cannot find a simple solution so they converge on the same location without forming some overly complex formation. The ideal goal would be a Starcraft 2 AI navigation
Problem #2
Using Detour AI Crowd Controller does a poor job enabling units to move around obstacles; often waiting to detour until the last moment creating a strange slowed down crawl around the obstacle, or a strange jittery mess. Disabling Controller Rotation in the Class Defaults solves the jittery issue but not much else.
