I had a probelm with the game constantly screwing up and corrupting every single previous save file prior to saving inside the homes of the Hearthfire DLC.
I found the solution to this annoying problem.
I found out what ONE major problem was. I turned off ALL autosave options completely. That helped stop a lot of the glitch and bugs. I also turned off all power saver options on my PS3 console which helped. Also... I realized that the armory mannequins in Hearthfire (or the mannequins just in general) are extremely buggy as well and caused a lot of problems. I also stopped saving INSIDE the Heatherfire homes which helped a great deal. All the corrupt files kept happening from saving inside the Hearthfire homes. So... Don't use mannequins (at least don't build an armory) and turn off all autosave options and all power saver options and don't save inside the Hearthfire homes. It seems to work a lot better since I've did that.
Thanks to any who replied or read this. Hopefully this helps someone else who may read this.
Nope. As far as I'm aware, there isn't a way to get rid of the mannequin or any of them for that matter. One or two mannequins shouldn't be too bad though. I have a major glitch with my mannequins though. I put clothing or armor on it and then take it off at a later date. I leave for a few days (game time) then come back and the outfit is on the mannequin again lol. I reccommend that if you have trouble getting gold, when you find a full outfit of nordic carved armor, put that on it then just keep coming back, collecting the armor off the mannequin and sell the armor lol. Not sure if anyone else is having this weird glitch, but I'm not complaining despite the fact that it is kind of annoying lol.
