4.7 Compiler breaks on custom events with duplicate args

If you create multiple custom events with multiple arguments that have identical names, eventually compiler gets confused and will stop compiling your blueprint.

Steps to repro:

Create a new BP, subclass of Actor.

In Event Graph, right click and add two custom events.

Edit each event and give them at least two arguments. Rename arguments so both events have same argument names.

It doesn’t always happen right away, but if you rename args on each event a few times, eventually it will break and stop compiling your BP.

Hey ,

I was able to reproduce this compile error in 4.6.1, 4.7, and our internal build. I have created a bug report for developers to look into (UE-7456), and I will let you know when I see an update. Thanks!
