Renaming collapsed graphs with period in name after copying and pasting crashes editor

Development Programming & Scripting Blueprint

Hi there,

Crash occurs if copied collapsed graph’s name was containing at least one period symbol. Any name variations have same effect, like “Test.”,“one.two” or even “.”

Repro steps:

  1. In any blueprint, using any node, create collapsed graph.
  2. Name collapsed graph “Graph.one”
  3. Copy paste it. It will be named “Invalid graph”
  4. Start renaming invalid graph, after any keypress on keyboard editor will crash.

Also invalid graph can’t be opened.

Tested on 4.14.3 , 4.13.2 ,4.12.5 - everywhere crash.

I have tried to find some info about that issue but found only “Bugfix: Fixed a crash when copying and pasting collapsed graphs” in 4.13 release notes.

Thanks.

Use a standard naming format of underscore (_) instead of a period (.). I.E. graph_One or graph_01.

I understand that there is dozens of ways how to format name. I have posted this issue here so people will see what may cause engine crash, and at least will know how to avoid it.
