title: Unreal Engine 4 EOS Plugin : Game crashes when calling ClearOnCreateSessionCompleteDelegates
body: <p>I have got login and logout working. I am now playing around with creating sessions. The session is successfully created, however in the callback for OnCreateSessionCompleteDelegates I call ClearOnCreateSessionCompleteDelegates to clear my OnCreateSessionCompleteDelegates. The game crashes at that point. I get a huge processor dump here is the top portion. I am on a MacBook Pro. UE4.7 and I am using the EOS plugin.</p>
