In the quest "What's Love Got to Do With It?", I am unable to target and attack the first "A Restless Lich" in the Nektropos Castle trapped room. I can see the name of the mob, but cannot target and attack it. This is preventing me from continuing with the quest. In an effort to mitigate the issue, I have logged off, exited the dungeon, and lastly, I have reset the dungeon. None of these have made any difference. The mob is still untargetable. Finally in desperation, I have Reported it as a bug both in game, and now to the forums. I have a screenshot if you need it.
