A player was able to exploit my non-experimental mode game and have every client lag in a way that they lost connection. It happened to me twice in two different places. When the networking loss occurred, you could hear a spam of character sounds. Sounds such as character splashing could be heard even though there was no water, and death sounds could be heard even though no one seemed to be dying.
I am assuming that the mass sound spam was caused by an exploiter, and I assume that the mass sound spam caused connection to the server to be lost.
