I sold off all the ruststones except the Great sword one and kept it in my bankbox thing, and im still continuing to do quests to try to reset it from a stupid iron sword to a rusted sword but still not luck i don't know why it wont work for this sword and it worked for all the others i have all the other rusted weapons and i got them after like 1-3 resets of the weapons.

Is the great sword different or something, btw this is MHF1.
Can anyone help?

Also ive been reseting the weapons using both G quests and the elder combine item potion quest does it not reset the item if i do G quests?
