I had dedicated server (on Windows 10) hang too today. Appeared so that i left the server for some time, and when i was trying to connect to it i couldn't. I hit Ctrl+C in the console window and to my surprise it didn't kill the server, propably just interrupted some task it was doing? I tried joini...

It seems this mod is not compatible with Advanced Turrets, they're using same name "sniper_turret" in item
