When you recieve the Empty Gem bag from Ping Fuzzlecutter in West Freeport you are supposed to place a diamond, star ruby, pearl, sapphire, fire opal, two enchanted platinum bars, and a special fire emerald into the bag to combine. Right now the bag combines using a regular fire emerald.
In Firiona Vie giving a fire emerald to Drake Mountainstorm for the special one you should need to combine the bag gives the error message "Got a bogus item, deleting it".
