Bugs happen, it isn't easy to find them and to correct them. They thought it a better idéa to release what works and then add in the things that doesn't work atm. What is so wrong with that? You get stuff instead of nothing and you know they will come with the pathfinding patch!
+I'm having a good time with DoF now and so seems many others to have. So why complain eyy? Be patient let them get it working!
