Get Class Defaults node disconnects output pins when project upgraded from 4.11 to 4.12

Upgrading a project from 4.11 to 4.12 causes Class Default nodes to disconnect their output pins from other nodes. If the node is reconnected and saved, it will disconnect again when the project is closed and re-opened. Replacing the node with another class defaults node does not fix the error.

Regression (Yes) issue (does not) occur in 4.11.2

1. Download, unzip, open project at link (4.12 version):
