Sierra Madre Souvenir Aficionado

Sierra Madre Souvenir Aficionado is an achievement/trophy and challenge

Challenge requirements
Find and collect 500 Sierra Madre chips.

Effects
Grants 150 XP and the Sierra Madre Souvenir Aficionado achievement/trophy upon completion.

Locations
Sierra Madre chips can be found mainly throughout the villa in fountains, while inside of buildings they can be found in dressers, night stands, and on tables.

Alternatively, collecting the Sierra Madre snow globe will award 2000 chips and complete this challenge automatically.

Bugs

 * Dropping chips on the floor and picking them back up will result in the cumulative figure of collected chips rising by that amount. For example: Dropping 100 chips, and picking them back up 5 times will result in the achievement unlocking.
 * When picking up the 500th chip the game will crash. When looting the 500th chip from the container you will no longer hear gunshots/footsteps/collar beeps/dialogue/etc. Also, the 'Esc' key will cause the game to freeze/crash.
