I'm a hobbyist at programming so I'm sure I'm missing something very simple:
Basically I have a script that has a method for repositioning a 3x3 grid of tiles every time the player goes out of the center tile. They are ordered in a List 0-8 left to right, top to bottom. The strange thing is it works perfectly for tile indexes 0,1,2,3 and 5, but the bottom row doesn't re-orient the tiles correctly even though it's using the same method that works for all the other tiles.
No errors thrown in the log.
Here is the method I created and the switch statement that calls the method. TilesArr is instantiated in the Start() function and is declared in the script class itself.
