Hi!

I have found that Using ALT drag method to duplicate Blueprint actors in level appears to break logic on new copies.

 ![38340-setup.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/0/5/105962e3a5d5cbde82eb5b9f50c6889f90ea0418.png)

setup is to have a simple cube blueprint that prints it’s own name when you collide with it.  
one on left is original. I then Duplicate it twice using ALT drag method.

Blueprint logic looks like this:

 ![38341-blueprint.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/c/8/9c868081decb9410995cf2de00e16efe886a08e1.png)

When you collide with original, all things are fine (See Log window on Right):

But Clear log and walk through third clone and you get this:

 ![38343-logforrightcube.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/d/a/6da77451f256ef4aba6e82e4869acf9650d78e46.png)

I ONLY collided with Visible\_Trigger\_Blueprint3 but it prints three messages one for each of actors.

One collision. Three executions of blueprint.

Weird, eh?

Hi ,

This sounds almost exactly like bug reported here:

which already has a bug report open for it (UE-11819). I have added your information to bug report and increased community interest in it. We don’t have an estimated time for a fix yet. I’ll let you know as soon as I see an update on it.

Thanks for your report!
