Adding Array Item Crashes UEFN?!?

Summary

When I add an array item to my creative_device it crashes when I try to add a 3rd item. Adding 2 is fine, but when I click the + button to add a 3rd element UEFN fully crashes and gives me the shown crash report.

Same Issue!

Thank you, we’ll get this to the right team to take a look.

I was having the same issue, though I was able to track down the cause of this.
I had a “Sequences” array inside of another “Sequences” array. By renaming the inner array to something else like “Instances” I was able to prevent the editor from crashing. This issue appears to be tied to naming conventions.

Ohhh… that might be the cause of mine as well actually! Thanks!

This fixxed it for me, thank you!

I had an array called “Components” inside of an Array called “Components” aswell.
