Hi,  
I’m sure this has been reported already but since I can show how to reproduce it easily and how to fix it I thought maybe I should report it while providing a fix for those who are having the same issue.

I have a 2 minutes video where I show the problem and how to fix it, I’m sorry if I was not coherent enough, English is not my native language.  
**Here’s the video:** [Here](https://youtu.be/R4kBzgGE6s8)

**To reproduce:**

1. Start a new third/first person  
project
2. Check the “Run dedicated server  
option” with 1 client (1 client is  
enough)
3. Create a new actor blueprint and  
add a collision box, uncheck hidden  
in game to see the collision box in  
game.
4. Add OnBeginOverlap, drag a pin  
and add Has witch authority and drag  
from Remote (we’ll test with clients  
only) and print something to the  
screen to see when a client  
overlaps.
5. Run through the box collision and  
you’ll notice sometimes you get 2 to  
3 overlaps, sometimes you get an  
additional overlap just after  
exiting the area.

**To Fix:**  
In the overlap event add a DoOnce node, use it to print something for example then reset the DoOnce after a delay of 1 second (you can get away with less delay)

PS: If you handle the overlap on the server only everything work just fine.

Thank you and keep up the good work.

Hi SenToRious,

Thanks for the additional repro. This is a known issue that is logged as [JIRA UE-30816](https://issues.unrealengine.com/issue/UE-30816). It is currently targeted for a 4.16 fix.

Cheers,
