I was in the Gnomish mines getting to level 5 to dip for Excalibur when a Gnome fled and I let him be due to my code of conduct. Went down another level and destroyed some more gnomes before coming back up. "Another" Gnome tried to attack me and when I killed him it called me a caitiff. That was the Gnome that fled from me...
How am I supposed to know that so I can avoid it in the future? I wouldn't have attacked him if I knew!
