I have an issue that unreal is crashing when I try to open 2 or more player clients (to check replication in game etc.)
The program crashes with the error Assertion failed: DeveloperSecretKey.Len() == 0 || ClientSessionTicket.Len() == 0
I have set the Developer key in the project settings (this makes it crash) I also tried setting it in the level bleuprint and it still crashes.
If i use 1 client then it is fine but I would like to be able to open multiple at once to see the interaction between different players (animations etc)
Any ideas how to have 2 clients in standalone mode with the dev key set?
