I wanted to add that I noticed that on other weapon system computers and I think I can crash game on basicaly any attempt of interaction with that block. I did managed to connect one time but I think it was when I was out of build mode, but I cant remeber correctly. If you need any additional help , just send in mail and I will try to assist any way I can. Last note I am new to this game and my pc is rather old, but when I play on server it goes rather smoothly on my low settings.
