Null Mesh?

I am getting a blank screen and the following error on Unity 2018.4.5f1:
ArgumentNullException: Value cannot be null.

All the modules are in place and I can see the Neo prefabs in the hierarchy as well.
I don't recommend using this project as a reference. ECS/DOTS has been changed greatly, so that this project is not useful any more.
If you still want to try this project, could you check if it reproduces on Unity 2018.2? I guess there are compatibility breaks between 2018.2 and 2018.4.
You are correct. The problem was in the way they changed the ECS/DOTS implementations across the versions. I installed 2018.2.0f2 and it worked perfectly. Thanks for sharing the wonderful projects btw.
Updated.
