I've been playing it again and there are still lots of bugs. Some of the old ones are fixed, some aren't and there's some new ones. I tried eating the meal and could not see any difference in the "final" room. In fact, I could not see any difference in anything. It just looks like you start again.
Anyway, I've got the treasure and I'm stuck in the "final" room. That's the one with no description, no objects, no nothing. Have I done something wrong to make it unwinnable or is there some magic verb that I'm supposed to guess? The only thing I've found that provides any useful feedback at all is THINK, but that works anywhere.
