So ive noticed theres a strange combat bug kinda of hard to explain but ill try.
If i am in PVP combat with 2 players, lets say mage and warrior (im an undead rogue). If i kill the warrior, and the mage has BEEN in combat with me for the duration of my fight with the warrior. As soon as the warrior dies my combat drops (i didnt vanish or do anything to exit combat). Obviously as soon as im hit with another spell or attack i regain combat but ive had situations where i get hit with a spell. I kill my main target and immediately drop combat. And i can restealth for free before the next spell/hit actually finishes .
