Set Members In Struct node does not work

Agreed, this is a major bug that has persisted for over 3 years!!! It should not take multiple workarounds to create a simple two dimensional array and make changes to values within it. Why need for a struct at all, why need to agonizingly create a temp array and than copy all old values over from original to create your new array in which you just want to change a single value. Bad show Epic, please help us with this asap.
