Initial findings: index for handling the current/previous game is off by one.

Initial fix stops the crash and game switching works, but looking at the array of "games" there is an Undefined game in the "1" index.

[0] Game 1
[1] Undefined
[2] Game 2
[3] Game 3

Need to trouble shoot how that array is getting set and fix the collection so that it does not skip an index.
