Index -1 Received swap message with child index Server Error

Hello guys,

So today I come with an issue that’s been bugging me for just too long. We’ve tried troubleshooting it but find no luck in solving this…

So the situation is the following: In our game, when a character is killed by others, all other controllers are disconnected (as all return with the message Index -1 Received swap message with child index), trying to take possession of the pawn (also spawning the UI and thus requiring them to reconnect to the server to regain functionality. What I don’t understand is why is this happening.

I will post images of the logic of what occurs when a character dies.

All help is greatly appreciated. Thank you!

Hello bryst_m153 ,

Sorry for the delay on this one.

After looking through your blueprint, I didn’t notice anything immediately apparent that could be causing the issue. What would be great is if you would be able to reproduce the issue in a clean project in its simplest form and provide a set of repro steps that we can use to see the issue on our end.

Not sure what I did… but I think the problem is when casting to the game mode to register the kills. I disconnected it for a build (by accident) and I’m not facing it so often anymore…

I’ll get back to you in the beginning of next week if I have a more detailed outline of what’s going on.
