Thanks for your answer, Raze, but this effort is a bit beyond my technical expertise. Since I've already finished the main game, I'll just bypass this dungeon and go on. I did successfully complete dungeon 4 in this same battlefield, but ran into another strange event on the third level. I killed a boss monster named Veath, but none of the merchants had given me a quest to kill it or retrieve any loot from it. I only got 3 quests out of the 5 merchants. Oh well, on to dungeon 5!
