Description

A crash is occurring if you collapse a node and name the collapsed graph something that contains a period. The crash occurs if you copy and paste the collapse graph, and then attempt to rename it. It also occurred by simply right-clicking on the collapsed graph node.

Steps to Reproduce

Open the editor
Create a new actor blueprint
Add a Print String node
Right-Click the node->Collapse Node
Copy the collapsed node
Paste it
Right-click on the duplicate node or attempt to rename it in the Details panel

Result: Editor crashes
