ToME WikiShrikeDeCil: Piles of items are sometimes reported in a messed up fashion. Running around in Erebor with a high powered Manathrust -> lots of larger dragons -> lots of overlapping piles -> this happens pretty frequently to me.
Here's one specific time, with as much detail as I can add.
Note line four of this message recall:
You have no room for a Ring of Constitution (-3) {cursed}.
You destroy a Ring of Constitution (-3) {cursed}.
You have found 17 gold pieces worth of silver.
You have no room for (nothing).
You have no room for an Ancient blue dragon corpse.
I was running around crushing various crud dropped inside a 'checkerboard' small room half filled with lava on Erebor 3100ft. The ring of constitution was in one square, then I moved onto a square containing both the corpse and the silver. But the message about the corpse didn't show up first - just the two messages about picking up the silver and '(nothing)'. Moving sw then ne meant I got the last line - the first indication there was a corpse there.
I'm a Gnome Sorcerer with Identify with a 2 square 'identify ball centered on self' that I fling around a lot. So everything in one of these piles of crud is typically identified before I ever enter the square of loot. I've had this happen about once per dive, fairly reproducibly. But I don't see what specifically triggers it. One of the lesser vaults filled with Wyrms meant a very large pile of stuff near the wall I was sniping from, but it didn't happen. Then the one I caught the exact message text from (above) happened with just one set of coins and one corpse.
I'm also running with the automatizer on, and a very long list of corpses to crush.
