Hi there!
Working in UE4.23.0 i met a bug.
In case when Material Editor custom node has more than 6-7 inputs, and i try to edit something in there, UE editor crashes. It is constant bug, and can be reproduced easily on UE4.23.0
Steps to reproduce, for example:

  1. In Material Editor, add Parallax Occlusion Mapping node
  2. Open this node in editor to watch POM’s internal nodes
  3. Find in there Parallax Occlusion Mapping custom node, that has 12 inputs
  4. Try to edit the code, or some input names, or etc, no matter. In a couple of seconds editor will crash.

In older versions of UE4 custom node worked well.
Thanks.
