[BH] Small Business preset not saving properly/Error 13

Experienced this save error for the first time last night. Assuming it's related to B&H since I did in fact create a small business for my sim, but can't be sure. I sold the business but still couldn't save normally. However, I was able to 'save as', creating a duplicate save file. The original version did not save at all, but the duplicate did. I repaired my game after I confirmed 'save as' worked and then went to bed.

I tested it again tonight by going into the duplicate save and picking up where I left off and remaking the business. I'd saved the business presets the night this error occurred. However, they were not saved. This time, I did not save the presets, which was the only thing I did differently from last night. The save code error did not appear and I was able to save my game through several hours of building and some minimal gameplay. 

I've never had this error before and I've made plenty of small businesses and the only thing I can think of that was different last night was saving the business presets. I've made three small businesses within the same family on the same lot without any issues before, so this was a frustrating experience.
