The Blueprint and Picture should speak for it self … The OnPickedUp function just calls Destroy Actor … I Pickup this Items on spacebar press. The Pickup itself is working but I dont pick up all Items in range. The ingame Screenshot show a much too big Box Collision(its almost bigger than the level itself to ensure all items are in) … all Items are within it! Now when i hit spacebar some items dissapear BUT NOT ALL they dissapear in a distinct order and i can make them all dissapear by just hitting space a few times and i dont even have to move so the Box isnt moving. I dont get why they are not found all in the first spacebar press … Am I missing something on this simple blueprint ? ![38275-blueprint.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/9/a/89a328dac8c6074e77a92fe61fffe03ffcc3d226.png) ![38276-game.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/d/b/6dbc7b93941f12b1823a2415f511a2eacb74b4db.png) ---

Hi L1ne, Thank you for the report. I was easily able to reproduce the issue so I have created JIRA report UE-13672. Our developers will be investigating it further and we will post back here with updates as we have them. As a workaround, I noticed that if you add the overlapped actors to an Array then loop through that array, it will work correctly. ![38338-getoverlap04.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/b/e/2bebb0b0adce243ad2a89e2a1d754de11175d871.jpeg) Let me know if that works for you. Cheers, TJ ---

Works now with the array. THX ---

L1ne, I’ve been working with one of our devs on this and he explained that this is a common misunderstanding and the expected behavior of the GetOverlappingActors array. The array that’s created by the GetOverlappingActors node isn’t ‘set’ like a standard array. The size can be changed each time a ForEachLoop is iterated. Because of this, with each loop the array size changes leaving behind some of the overlapped objects. This is a little hard to explain in just text so if you would like me to go into further detail, just let me know. Anyways, the workaround that I gave you isn’t a workaround, it is actually the correct way to implement this. Cheers, TJ ---

I would very much like to hear more details about this! I assume it applies to all functions that have an output TArray parameter? In what case would this array be changed as you loop over it? ---

This is inconsistent behavior and not documented clearly, how is this a Non issue? ---

Reporting, this workaround doesn’t work when I use SphereOvrelapActors in a AnimNotify. It works only in an Actor. ---

Can I just say(If I can) thank you for the workaround and I have some info on it that could help(if it’s not too late). I noticed that it’s specifically half the actors getting missed, and it only happened for me when the mobility of the actor was set to moveable, thanks and I hope the info helps! ---

I just came across this issue today and luckily the workaround works 🙂 Just for the better context: the easiest way to explain such behaviour is that the “GetOverlappingActors” is a Pure function, that means it is (probably) called every for loop iteration. So the “workaround” is not workaround but a valid way of handling it. First - copy the result to local array and then work on that copy without calling “GetOverlappingActors” every time.
