By the way, something that's a bit annoying and probably worth knowing if you want to loot chalice dungeons for blood rocks or chunks using that Google spreadsheet:

You cannot loot the same item more than once if it's the same type of chalice.
I tested the glyphs rpzkeauc, 3nawt3ys, and fmu9qx9g. All three are Isz chalices, and the second or third one (I forget) is actually Rotted or Fetid even if the document doesn't say (it said it was when I created the glyph). The first two say they have a Blood Rock on layer 1, and the third one has one on Layer 2.
I looted rpzkeauc first, and got the loot it said. In the other two, however, both times the sarcophagus revealed only a Great One's Wisdom.

I explored all bonus rooms and looted all the chests, just in case.
So yeah... it needs to be a different chalice type. I looted a blood rock from 4292egu2 which is Lower Loran. I don't know if Depth is related (would a blood rock even spawn in a depth 4? all of those are depth 5), but if not, it means there's a maximum of 3 blood rocks you can loot in chalice dungeons; one from a Pthumeru dungeon (probably Ihyll only as it's depth 5), one from Lower Loran, and one from Isz.
I understand you can't loot more than the same rune, but it sucks for blood rocks or chunks.

They're rare enough already, dammit. Needless to say, dismantling the glyph and remaking it doesn't work either. Funnily enough all the other loot does respawn if you do that (usually just blood vials, bullets or ritual materials) but not the sarcophagus loot, it just turns into a Great One's Wisdom.
Where can I find a
exactly?
I killed
There should be one right outside Cathedral ward, front door where a crow is hanging out near the stairs.
I found her, did the duel, and the lamp still didn't work after. Consequently I think the lamp bug is unrelated to her disappearing.
Didn't bother me too much though since the next lamp is so damn close anyway.
I don't care much about the lamp either, but it's very confusing because you expect something to be going on there and there's nothing.
