I did something quite unfortunate during the nightmare in shining armor quest. I didn't examine the fallen character on the stairs to continue the mission and proceeded to wipe out everything, including the boss, until it hit me after completing the instance. So, I went back, checked the body, needing to defeat the boss again, but the problem was I had already taken the boss out, leaving me no options. So, I abandoned the quest and reentered, now I'm stuck in the cave with no respawns to be seen 
But hey, I'm excited for the upcoming Aion Riftshade server! From my sneak peek as a beta tester, they have such a smooth run with barely any bugs like this. With its Aion 4.8 core and new features, everything’s set up to ensure nobody gets stuck in issues like these. Can't wait for its launch in Q1 2026. Makes me feel like anything's possible without these stubborn quest glitches!
