then you're in trouble. Are you sure, you meant the thieves? They were friendly at first!

Did you mistake them for assassins? Sometimes these groups mix up and maybe you killed one thief accidently and all turned hostile afterwards?

You weren't supposed to kill them and IIRC in 1.0034 there were no thieves in the sewers anymore <img src="/ubbthreads/images/graemlins/think.gif" alt="" />

Well, in any case, your reploss is due to killing innocents = > thieves in the sewers.
