Scripts are written by Tribal Wars players, it's not InnoGames's responsibility to maintain them and therefore this is not a bug.
Anyway, below is a script I've made and it's working on this version. You could try it if you want:
Code:
javascript:var text='test';
function redenumire(){$('.rename-icon').each(function(contor){index = contor < 9 ? '00'+(contor+1) : contor < 99 ? '0'+(contor+1) : (contor+1);$(this).click().click();
$(this).parent().next().children().val(index+' '+text); $(this).parent().next().children().next().click()} )
}redenumire()
You should replace test with whatever text you want.
