Error in the script "Game_Map"?

[FrozenNuke0327]

I was creating a map (https://www.dropbox.com/s/bmd9osyvq0a8pxn/map.PNG?dl=0)

..A Forest with branching directions.

However,

When i attempted to walk around on these tiles, it would work for a moment, then the game would crash and give me this error screen (https://www.dropbox.com/s/au3znhokkijiqb5/Capture.PNG?dl=0)

If there is a way that i can fix this, please make sure to let me know!

EDIT:
I previously have tried copying an additional copy of the Game_Map script i had, directly into the current project, It still gave the error screen.

I searched a bit around and apparantely you can get this error when you delete tiles from the tileset, but forget to erase them from the map. I suggest going over the area where you get the error with the top-left tile (the empty one) and see if that helps.

Neat!

The map is working fine now, thanks!
