[crossfire] New layer code bug :)

Not exactly the case Nicolas describes, but try the following: cast
counterwall and walk in it. You'll see yourself disappearing. (This
works for any spell I've seen)
Or find a pile of treasure and step in it, you'll likely have to search
for yourself :)

I guess so as wel. (AFAIK it is the only way to be on a tile with a
trap!)

Not only levitation boots, but the Feather Crown (Neurmberg Receiption
towers), diamonds and rubies as well (but not emeralds and sapphires).
Pearls are different matter. They won't hide the player when there are
only pearls, but they will in a big pile with other items.
You cannot simply reproduce this effect by staying on a pile of
diamonds/rubies - and what i'm saying now contradicts a few lines above
- but if there are several 'diamonds' (not big ones) that won't stack,
they will hide you. Same applied for rubies and even flowers. I guess
these items are identical, but I cannot check that, I'm not a DM on
Metalforge ;)

Perhaps the player should be drawn in one of the highest layers? (such
that they remain visible in a pile of treasure as well as in spell
effects)
