Successful Cooked build error "package is uncooked"

Hello ,

Thank you for your reply, I am using 4.10 preview build 4.

I have not tried it with another template, but will on one of the other test projects using the same version.

The level is a multi-tile set, using the world building option and has 248 tiles in the build to create a 6300sq km map, I am not sure which map should be used as the load for the ‘Maps & Modes’ under ‘Project Settings’ but all maps were included.

Yes all the levels were included in the cooking process

Any further suggestions or recommendations are appreciated, thanks!
