Add logic to validate the game state to detect problems that cause null-reference exceptions and index-out-of-bound errors in the game's Update code. If it's efficient enough, possibly revalidate state after mod events so we can show meaningful errors:

PineApples Everywhere incorrectly changed game state, which will likely crash the game (detected location 'New Location' with null map).

Example errors:

• NullReferenceException in update loop (log).

The scope for this task is too broad; smaller tickets will be created as needed instead.
