So, just found out today that there's literally no security checks on servers to prevent client-side mods from impacting the gameplay of others. People even have the ability to fully edit terrain and buildings on servers, even spawning in massive structures or digging massive holes, with zero admin and no server-side mods installed.

How and why was this never addressed? /facepalm

There are mods that give the admins more controll over there game/server.
But this is a coop game, not a true multiplayer.
