    Invallid packet crashes the UT4 game server

    Recently we've had crashes with our UT4 server. The hub it self stays active, but the spawned game 'room' or 'server' crashes.
    I have no option to reproduce this behavior.

    This might be related to this topic: https://forums.unrealengine.com/unre...e-server-ddos/
    If this is really related to that topic, it could either be that the UT4 is still using the old borked UE4, or the problem isn't fixed properly.

    Please can someone look into this?
