What ever was installed has made op pvp lag that bad, it takes me 4 times to jump down from spawn from that many lag backs and I'm not the only one having the lag issues as others complain about it also, there was a bit of lag to start with but now it's just terrible, there are also player ghost flying around my head and it is quite annoying while pvping someone. It sucks because the plugin that was added was meant to fix the problem not make more.
