Description

On line 1691 of TileBase.as a local variable n in created which is then not used in the rest of the function.

var n:int = listItems.length;

On the following line 1692 there is a for loop that gets the same value listItems.length

for (var i:int = 0; i < listItems.length; i++)

It's fairly obvious looking at those 2 lines that a performance enhancement has tried to be implemented without being fully checked.

My suggestion would be to change the 2 lines to read as follows:

var n:int = listItems.length;
for (var i:int = 0; i < n; i++)
