My test project worked fine in 4.7 preview 3. After upgrading to 4.7 preview 4, I get following errors when trying to compile my project in VS:

Were there recent changes to AController::GetNavAgentProperties and APawn::GetNavAgentProperties? Did Navigation get moved into a new module?
Edited:
I deleted my intermediate files and did a full rebuild and I was able to compile. Now I am getting same Assertion failed: InstancedRenderData.InstanceBuffer.GetStride() == sizeof(FInstancingUserData::FInstanceStream error else is getting.
