Sorry for crossposting, but I desperately need an answer...
Trying to get a Lambent Star Ruby, my lvl 11 Wood Elf Bard handed two Star Rubies and a Lambent Stone to Genni in Temple of Sol Ro. As stated, Genni ate the Lambent Stone and gave me the two Star Rubies back... Is this a bug or can the hand-in for Lambent Jewels fail? It worked fine for a Lambent Fire Opal (for which I handed in the Fire Opals and another Lambent Stone afterwards).
Genni cons indifferent to my Bard, so this shouldn't be a problem. The only other thing I can think of is that it didn't work because I bought the Star Rubies in Abysmal Sea, and didn't get them as drops... Anyone?
