Gnome Guards all asleep
 

Gnome Guards do nothing when a poor gnome runs by with runaway clockwork chasing them.

If you think this is a bug, post it in the bug forum. Otherwise I have noticed that there are certain mobs that guards won't touch.

Gnome Guards have feelings for their rogue contraptions obviously

Yup happend to me just yesterday on pvp server..however ...ive never played a gnome so not even sure if its supposed to be like that
