Okay! I've fixed it. sort of. The character spawn point not working. so I moved the terrain under the PUN default spawn point. Mountain to Mohamed so to speak :)
This is the most annoying piece of software I have ever encountered. I've made an external behaviour tree but now can't load it into my prefab? What to do?
This is not obvious and needs to be addressed. It is incredibly annoying that this matter is not covered in the tutorials. This has put me off using Opsive products in future!
