If a child blueprint attempts to set an array element of self to an array of the parent blueprint, then the editor is saved, closed, reopened, the self pin will disconnect from the Set Array Element node.
Steps below copied from Mike Schoell as they worked consistently to reproduce:
1. Create a BP (MyBP)
2. Create a child BP based on MyBP (MyChildBP)
3. In MyChildBP, add an array variable of type MyBP.
4. Make the attached graph. ArrayOfParent is the variable I created.
5. In MyBP, add a variable of type MyChildBP.
6. Save both BPs
7. Close and re-open the editor. Open MyBP first.
8. Open MyChildBP and look to see if "Self" was disconnected.
Results:
Self pin is disconnected.
Expected:
Self pin is attached to Set Array Element node
