Log: [http://pastebin.com/vzu1948z](http://pastebin.com/vzu1948z) I’ve modified the Shooter Example. My PIE runs fine with a single player, but when I use 2 (single process) the editor crashes when the client exits. It only happens when it’s the client, and the log complains about one of several things(some pawn, a brush, or a weapon for example). The error is always “Object from PIE level still referenced. Shortest path from root: (Object is not currently rooted)”. I don’t have any references to actors stored, and I certainly don’t have any brushes stored away. I believe this is a bug somehow. Perhaps my character’s replication is doing something weird? Once again, I’m not storing any objects anywhere so I don’t think my replication is the cause. Anyway, I’ve been unable to figure this out. Any ideas? ---

Maybe try deleting all the BSP brushes in the map and see if the crash goes away. ---

Hi viperld, Did you modify the C++ or blueprints portion of Shootergame? How are you running your replication between client and server? ---

I’ve extended the C++ and created my own character (from “ShooterCharacter”), pawn (from “Pawn”) and weapon (from “ShooterWeapon”). I’m also using blueprints of my classes in the level. For instance, “BP\_MyCharacter” to extend the “MyCharacter” class. Replication settings have generally be copied from the base classes (this is all serving as an applied learning experience for me so I don’t reeeaaallly know how to properly replicate yet). There’s the health, current weapon, ammo, etc… all the things from the Shooter classes. ---

Thank you for your response, but I should clarify that the crash isn’t always caused by the brushes. So far the crashes have complained about either the brushes, my weapons, or my pawns. At first I was confident that I was doing something wrong in my code because crashes complained about my creations. However, when it barked about the brushes I began to think there was something less obvious going wrong. ---

We have a tutorial on replication here: > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — https://unrealcommunity.wiki/! You will be able to find content from... However, the error you are receiving has a lot of mentions to dividing by zero, do you have any instances of this in your blueprint or C++? ---

I am not near my project right now but I will certainly check when I am. To clarify, I’ve mainly got replication happening in my C++ and not in my blueprints. ---

I realized I was using a non-source project so debugging is only showing me so much. I’m setting up the project in a source build now. I’ll be back with more info. ---

Unfortunately this is not a real answer. This did however resolve my issue. I was running my game as a modification of the ShooterGame obtained through the launcher. I decided to compile the source myself so that I’d get full debugging messages. I no longer receive any crashes when exiting the PIE as a client. Once again, after migrating my game over to a source build I no longer experienced any crashing from my client’s exiting the PIE.
