UE 4.11 Dedicated server crash PIE.

Question

Greetings 

We've noticed a bug in the code located in AKaudiodevice.cpp. The problem is when you run the game in editor and have dedicated server running it crashes the entire game.  Regardless if the project is new or old.

^ These are errors from two separate projects one brand new and one that we have been working on for months. Each has it's own separate engine. 

My coder seems to have isolated the problem, it seems as if the listener is calling prior to the server populating. Ergo returning a listener as null. He suggests, from what he can see ; add a null check in the loop or the function does not get called until there are valid players. There could be more problems, but we noticed this when we were updating from 4.10 to 4.11.

We added the null check...

if (PlayerControllers[i] == nullptr)
    continue;
