Ushi No Tane - Harvest Moon

I am trying so hard to get all the cursed tools in the winter mine and so far I have the cursed fishing rod but every time I go down the mine, I don't seem to be able to get past lever 9 except for that one time I got down to level 29. I get all the way down and then find that there are no stairs. I don't understand why this is happening. I am in year 2 of my game about to start year 3, I'm married, I don't know if this information helps but Yeah, I'm getting so frustrated now. Does anyone know why this is happening or what I can do about it?

Do the old save reload trick-you need BOTH files for it. One is to make sure you get the stairs, andc the other to make sure you find the tool. Also, make lots of elli leaves (replenishes ALL stamina and fatigue) the recipie should be on the main website
