wrap content scroll view Transform error

[firestorm]

I have a store set up that is just items in a scroll view. I want to delete the item if the player owns that item already. The issue is I get this error when you attempt to scroll through the items after them being deleted

MissingReferenceException: The object of type 'Transform' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

I have attempted to run the WrapContent() after deleting the item and the scroll views ResetPosition() with same results

any help would be appreciated

UIWrapContent script caches the list of transforms. If you delete some, then the wrap content's list will be invalid. The caching of transforms is done when calling SortAlphabetically() or SortBasedOnScrollMovement() functions. Just call one of them after deleting your transforms (my guess - alphabetically in your case?)
