Canda 3. explosion/ nuke / hack?

[Rawson 0]

spawned in canada 3 server. about five seconds after turning around in cherno i see a giant smoke collumn. i go around the wall to see the horizon engulfed in flames. Im still fairly new, but this deffinatley is not supposed to be in game. Heard other reports of "nukes" killing entire servers so i figured id put this up

You can cause a nuke you just increase the explosion radius.
