Why do I get CDO Errors?

When I set the class variables through a blueprint, not only do I need to create a blueprint just for setting a few variables, there is also a bug going around I heard that causes blueprints to reset those values to their defaults when hot-reloading. And the game auto-hot-reloads after adding C++ files and such so mmm… Not sure what to do here.

I also noticed that replacing the paths with invalid ones, doubles the amount of CDO errors (from 2 → 4).

And this function works in another project but not in this one. Odd.
