The game is in a terrible state right now because of how easy it is for people to send requests to the server and sniff packets.
There are mods that shows boss spawns and timers.
There are mods that makes character head size bigger.
There are hacks that allows players to equip multiple weapons in multiple slots.
There are bots teleporting straight to mobs and bosses.
Don’t you think that because your netcode is not very secured that the servers are lagging so bad?
