I just started a warlock and got my imp. What i just noticed is that when the agro changes between me and my imp, the mob bugs out and starts evading. there are now 4 mobs in orc starting-zone that just stands still with low hp but wont move.
Getting "out of combat" when it happens and the mob cannot be reset by attacking and it wont run back to its original startingpoint. It keeps on doing this, and it seems i can bug out the whole continent this way.
