I get as far as the exile colony level 5, where I'm to deliver the plauge
antidote and help the old man...so far so good.

Well, after I kill every thing around the old man still thinks there are
baddies around and he keeps on casting spells. When I talk to him he just
wants my help ??? but there is nothing around to kill.!!

I've tried teleporting back, saving and reloading I've also applied the
latest update...

not sure what else to do except... start again!!! hope not!!!

help please
