Ah, I see - I experimented the disappearing chest syndrome <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> for a short while. I had already found out in my very first game that chests turning dark are a problem. I normally have a chest near the Ars teleporter, cause I didn't bother with a house. But these disappearing chests in all of my games always came from the castle! I didn't have probs with other ones - if I wasn't encumbered, of course. If I was, I quickly dropped an item, cause I didn't want to lose stuff <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" />
Barrels are safe, if I didn't click on them in combat mode <img src="/ubbthreads/images/graemlins/shame.gif" alt="" /> - what I'd like to know: Did your disappearing chests come from other places than the castle? Or did they disappear if you were encumbered? Or if you stacked them and then took them up in your inventory? This bug fascinates me.
Sidenote: Nope, I'm not wise - German saying: Even a blind hen finds a corn <img src="/ubbthreads/images/graemlins/delight.gif" alt="" />
