Make sure your build is at or higher than the latest build posted below. If it's lower, verify the game contents to force an update. It's also important to remember that the sandbox depot is not updated regularly. This depot is only used for confined testing. If you were working with me on one of these confined tests, please remember to opt out of the sandbox depot so you're always receiving the most up-to-date build of the game.

Build: 1033242

Added "Packages" folder to address the issue where the Package list wouldn't function correctly without it existing.

A more permanent solution will be added into the game at a later build.
