Editor crashes on adding local variables to blueprint

Development Programming & Scripting Blueprint

I just found a bug with Blueprints in the 4.7 preview 1.

What to do:

  • Create a new blueprint, based on Actor
  • In the construction script, add a “MakeArray” node. Dont connect anything to it, but click the “Add pin” button twice.
  • Click on the left side on the plus adjecent to “Local Variables” to create new local variable.
    … which is not happening. Instead the editor crashes ungracefully.

In version 4.6.1 it creates a normal local variable, no crash.

PS: Some users report that it doesnt matter if you add a MakeArray node or not. The creation of the local variable is what causes the crash…

Cheers,
Klaus
