Sorry if you see some mistakes, i am not a native english speaker.
I don't know what is happening, but i tried EVERYTHING, reinstalling Unturned, requested a new VPS, changing version of Linux Distro (Ubuntu), checked prerequisites, reinstalling prerequisites, etc etc. But nothing seems to work. When i execute the start.sh file, everything it's fine, until it reaches the Loading Map Assets part. When the console reaches that point, the server freezes and several minutes later, BOOM, crash. I am running my VPS in Amazon EC2, it may could be them that are restricting something Unturned or Rocket needs, but i don't know. Any help will be greatly appreciated.
