I've already explained to Cavik about the lag, he blames the server for not having enough RAM but I'm pretty sure the server lags when someone does something it gets data called "Sassy", it's some ugly code and I wish it never existed. I'm guessing the more data "Sassy" saves the slower the results get, which is why the lag gets worse, even with a low amount of players.
When the server was launched it didn't have any lag. As the server started collecting more data it's been getting worse because of this method.
