Defense Grid Game update

A small update addressing a few bugs and usability updates:

• Cloud save and leaderboard capacity upgraded - leaderboards and cloud saves should now resume working for the players who have played Defense Grid 2 the most

• Chapter arrows in the UI have been made more visible and are easier to see

• In DG Architect, the two holo skirt brushes are no longer available as those assets were causing a crash

• Additional code for internal error checking and verification was added.
