I was developing in FB3 beta, and I was adding items to an array using splice. it was adding the elements to the provided index, and if it was greater then 0, it would add the empty elements as needed. Then I installed FB3 and it stopped added the needed preceding elements. so if the array was empty, even if I spesify the 3 index to put the item, it just places it in the 0 index. ugg Russ
