Hey ,
I have reproduced the issue and have entered a bug report, which you can track here: Unreal Engine Issues and Bug Tracker (UE-35512)
Thank you for your report.

Well thank you very much for that! I fav’ed the Jira just in case I come across other things 
The 4.13 looks really stable, I had lots of blueprint compilation crashes in 4.12.5 (because of how I coded, circular dependencies and stuff) and none of them occur in 4.13. I’m looking forward modifying a core Structure used in different places of the code to see if it reacts as bad as it was reacting before.
