Unreal 5.5 kept crashing when I was editing a scratch pad module

Assertion failed: OwningNode[File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Classes\EdGraph\EdGraphPin.h] [Line: 427]

I figured out that it happens when I try to create a vector to position node when dragging off of a wild card from a select / if node. Is there something specific I’m missing, or is this just something to avoid?

Hello there @GonkinDroid!

Checking with my peers, and investigating around the community, this is indeed an action to avoid. The error is triggered due the pin not being tied to a valid node, types should be pre-defined before connection.
