Packaged Game cannot resolve List of Pure BP Structs

**UE4 Version**
4.24.3

**SkookumScript Version**
4.24.03

**Describe the bug**
Trying to access a list of struct defined in BP fails in a packaged game.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a struct in BP
2. Add a List of this struct to a BP
3. Try to access the (add/remove) from the list in sk

Replacing the struct with a C++ struct works.

**Expected behavior**
BP based lists of structs can be modified in sk.

Start by reproducing the issue with UE4 4.24.3 and SkookumScript 4.24.03: create a Blueprint struct, place it in a list, package the game, and try add/remove from SkookumScript. Compare the packaged Blueprint-struct list with the working C++-struct case; done means Blueprint-based lists can be modified in SkookumScript.
