Opening a PM, Mass or even opening an empty message to PM somebody is really laggy. I deleted my whole Graal Online folder and reinstalled it and it was fine for a little bit, but it's horrible and even makes it annoying to play since it takes ~3 seconds to open a PM or mass message.
Seems to only happen on Graal Kingdoms, but figured I would post it here to see if anybody else experiences it on another server.
