Hey! i have just finished modding mine and a friends client, and im trying to start a server with all the mods we have used, but everytime i load it, it (sometimes) opens a window saying how many mbs its using, ticks, etc, for acouple seconds then will automatically close, sometimes it wont even appear, help? (edit: i believe it is because of mods not working on the server, is there certain mods that cant work on servers?)
