Hi, just watched your video, looks very nice indeed. So there were several things which was not actual bugs. I noticed you mentioned about castle. So I usually calling castle as a central building where king lives :) Also noticed you saw some workers dying in woods. I know what happens there but I will leave you to find yourself. Just a hint, keep looking closely around in the forest and I am sure you will find out soon :) . I saw there was one moment with camera, I think camera was in RPG mode, so when you clicked on that RPG button, it switched back to RTS mode. Looking forward for the next video and what new you will find :) .
As for crash, you can also create a video how you reproducing it and I could try exactly the same way to reproduce it on my computer.
