Looks like the map files and primal game data are still being cooked. However a lot of other files are no longer being cooked.
Here were my steps:
- Verify dev kit with launcher
- Update dev kit binaries from git
- Copy in the new files (https://drive.google./file/d/0B0d…ew?usp=sharing, mentioned in https://forums.unrealengine./show…13-9-on-GitHub!)
- Run TC cook
I updated my post for the individual issue…
