Household Stuck Loading

Update, I went ahead and tried something different. I pulled up my household's load file and opened it, but before I jumped into their actual household to play I clicked on another household of just 1 sim. That was able to load up very easily. From there I was able to go back into manage worlds and hop into my own household, which actually worked! Dunno what kind of bug this is or anything... But I'm just glad I was able to get it to work! Any advice on how to prevent this from occurring again, or any ideas as to why it occurred would still be greatly appreciated. I do currently have my 3 sims living in a larger house so I might see about downgrading a bit to help with overall application performance. Once again, thanks for any help you might give!
