I have completed all the sidequests for the gratitude crystals (and found all the ones in the wild), but realized I was still five short (75).
In trying to discover the issue, I realized the game had not recognized that I had completed the plow needed request from Kina, when in fact I had got Guld from Eldin Volcano and brought him to Kina (and received the crystals). But now Kina is again talking to Link about needing someone to plow the field, and Guld is back in Eldin volcano saying he wishes he could go to the sky.
However, I cannot get Fi to appear once again in Kina's presence to set Guld on my dowsing function, so I cannot get Guld back up to the sky. This has basically voided my ability to complete the Gratitude Crystals sidequest and get the Tycoon wallet, which seriously pisses me off.
Does anyone know how to fix this issue?
