do you have some custom mods installed or did u modded the core? i m no expert, but i think something in game core regarding clans is not right..

the only custom mode i have regarding clan is this

Code: Select all

that should make the NPE not appear

Code: Select all

setTitle(""+clan.getName()+"");

change to

setTitle(""+(clan!=null)?clan.getName():"");

he simply misplaced the code in the first place, no reason to add a null check if you can simply move the code further down.
