Ysolda, Belethor and Hulda.
Ok, starting from the beginning, many ingame days ago a vampire attack washed away Belethor's life from Skyrim's face. Back then I couldn't do much to save him, since I found him died when I arrived to place and I didn't know about the resurrection cheat.
I simply decided to accomplish Ysolda's quest and found her a mammuth tusk, I was told that if Belethor is dead and Ysolda has finished her last step from becoming a merchant, she would have took his shop instead of Hulda's Inn.
The only missing step was the town reset, that couldn't occur due to my continous visits to deposit new booty into my house.
So I decided to stay far from it for a while, used helgen's square to drop heavy stuff and free my weight, while I traveled to Ivarstead, moved to greybeards, completed several random and minor quests, moved in Falkreath, did the same there. Meanwhile my "trash deposit" grew out copious, becoming a little coloured mountain of stuff of every kind.
I started feeling the need of deposit all that stuff in a chest, stuff for a weight of 2000, specially after I got that annoying dog around me, that kept giving me troubles to drop more stuff, jumping everytime in the pile and throwing items away, or shoved my character into it to do the same thing (Seriously that dog could be scripted better... it's just a pain to have him around, he is schizophrenic).... I even think to have lost some item in the textures due to this and the weight of the upper items.
From 10 to 15 days passed, maybe even more than that, so I supposed the reset was already happened, looted up to 999 weight of items and transformed into werewolf to bring my character near Whiterun. Arrived there guards gave me the "welcome back", I noticed that the stand had back new leeks to buy, when I entered my house I found that child adopted a bunny, everything seemed fine and looked like the reset actually happened.
But, unfortunately, Ysolda still wanders like a beggar, Hulda is still in charge inside the inn, Belethor's shop is still closed and I feel like I only wasted time and suffered useless problems derivatives of my long time away from home.
Now I'm out of ideas.... Does anyone have an idea of what's gone wrong?
