Error Cannot access 'Cube1'. It is pending kill

can run my blueprint fine for 1, 3 sometimes 4 times then I get this error:
Error Cannot access ‘Cube1’. It is pending kill. Property: ‘Cube1’ from node Construction Script in blueprint Cube01
is this the garbage collector & is there anything I can do about it or should I worry about it?

using the Unreal Editor 4.6 release

using an ‘on begin overlap’ event to destroy actor

destroy actor works fine if I use a projectile and ‘on component hit’ event and doesn’t create the error

‘Cube1’ is an imported static mesh, I use a box to trigger the events with the Cube1 being the root

thx for any help

I was receiving a similar error when trying to kill a particular actor as it left a volume. My solution was to change how I was destroying the actor; rather than using a “destroy actor” node, I set the actor’s “auto destroy when finished” bool to true. UE lets the actor finish up whatever it was doing (in this case, I was adding a rotation to the actor) before killing it.

Hey, just wanted to say thanks a lot, that auto destroy when finished helped me solve a problem!
