EDIT

Ok, we have discovered the error: there was an infinite loop breaking the code. Nevertheless, this was only found thanks to Project Live Data. (UEFN - Content Service)

This means that UEFN was unable to flag the loop, causing the session to crash without any warning. This should be addressed as soon as possible to prevent such issues.

I’m having the same issue but I dont get a crash report!!
Not in create . fortnite, not in the Content Service, not in the editor, not in-game.. this is really bad. I’ve been debugging for a week.

The disconnect happens right when the round ends. When the next one starts it still says disconnected from the editor but everything verse or not works well. So not sure if it is something I should actually be worried about
