[4.6.1] Remove pin on split struct

Branch: Binary

Build version: 4.6.1

Detailed description of the issue: Splitting a struct in nodes that allow adding multiple elements results in problems when you use the “remove pin” option on an individual element from the struct. For example, if you have 3 structs in a sum and you remove an element in split struct 2, you won’t be able to remove element 3 or any of the remaining elements from the split struct.

Repro Steps

  1. Open a blueprint graph
  2. Add a “vector + vector” node
  3. Add an element to the node
  4. Split element 2
  5. Remove a float from element 2

Hello dissonanceint,

I was able to reproduce this issue on our end. I have written up a report ( UE-9912) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Now if you do the same think in 4.16.3 game engine just crash. In my case I added 4 new pin splited the 4th and then remove an option.
