Having the same problem in my Falkreath home. This was my second character build after installing Hearthfire about a month or so ago (we'll not discuss what happened to my first character). Anyway, I had no crash problems with my first character. The house was completely built and furnished (wings were, Kitchen, Alchemy tower and bedrooms). at the time I had no extra people in the house, save for my follower, Faendal.
On my second attempt, I had my follower, Faendal; my steward and housecarl, Rayya; and a bard. The house had an armory, greenhouse and trophy room. I had items on the mannequins (none of which were full), several plaques were adorned and I had a large number of alchemy ingredients, soul gems and smithing materials in knapsacks, chests and bags. the greenhouse was also in full use.
When i first started experiencing crashing, a friend of mine suggested removing the workbenches and it seemed to work fine. a few days later (today), I began experiencing the issue every time I entered the house and usually within 30 to 60 seconds after entering from the outside. Here's what I have tried so far, keep in mind, none of these fixed the problem:
- Cleared game cache
- Cleared system cache
- Left my follower outside while I entered (this actually seemed to work the first time I tried it, but crashed on my second entry to the house)
- Removed my follower completely
- Made Rayya my follower
- Attempted to remove my alchemy items (as this is the largest collection of items I have in a group), made it as far as to get the items in my inventory....then crashed a few seconds later.
- Removed all but my last 10 saves.
Any other suggestion would be helpful.
I really dont want to start this character a third time, but It would appear that this may be my only option. If there isn's a clear fix to this soon, I think I'll just uninstall Hearthfire and chalk up the $5 loss to my lack of proper research before buying.
