I started MG 3.6.0.2 on my intel i915 GPU laptop (which I haven't done for a while) and started to host an Internet game (port forwarding should have worked, since it did work before), and stopped hosting just a few seconds after I had started to host, then joined a headless server (summoner) which was controlled by player 'Ottoman'. As soon as I was connected to the server the game ran into a segmentation fault:
