Brief Description *

A bridge whose CF is lower than or equal to 1/4 the WiGE weight must collapse under it's size/load during a fly-over, however, due to an off-by-one mistake in code the function that checks if the building will collapse tries to reach for an element in an array at the position -1, causing an out of bounds exception.
