TLists Reporting Incorrect Counts?

I use it to keep track of number of tanks left in an old tank game I made. I have used it on 1.26, 1.28 and 1.30 and never had any problems.
I am using 1.30 at the moment.
I made a simple example to test it:

Local list:TList
Type TEco
	Field Forest:Int
	Field trees:Int
	Field animal:Int
	Field river:Int
End Type
list = New TList
For n = 0 To 500
	Local e:TEco = New TEco
	e.Forest = Rnd(5) 
	e.trees = Rnd(57) 
	e.animal = Rnd(350) 
	e.river = Rnd(4) 
	list.addlast(e) 
Next
Print list.count()
For e:teco = EachIn list
	list.Remove(e) 
Next
Print list.count()

everything works fine here.
