Can't Finish Novels

My Sims have developed an annoying glitch. They can't finish writing novels. As soon as the novel is completed, the usual message is displayed. I send them to start a new one, but the old one isn't finished yet. I set them to continue, they start writing, it looks like they restarted (by the completion bar), but suddenly finish, pop off to the side (sometimes there is another Sim working at the same table and they pop off to the side as well). I've tried many things to fix this glitch. This seemed to coincide with the addition of "Bluefunk_PicnicBlanket_Public.package".
- reset Sim
- reset Lot
- reset everything (with Master Controller)
- scrap the book and start over
- removed "Bluefunk_PicnicBlanket_Public.package"
- scraped the game and started new game
- scraped the world and reinstalled world (my own custom world)
- cleared caches
- scraped all worlds and manually removed all remaining traces
- opened in Create A World, added some generic house lots that came from EA (because I had to add them to my very empty world each time I play as well as fix the staircases ) and re-exported world and re-installed world
- removed all expansion packs, "The Sims", and Origin from my computer
- edited all traces from the registry
- restarted the computer
- reinstalled Origin and "The Sims" and expansions and other stuff (but not "Bluefunk_PicnicBlanket_Public.package")
- TSR RifFix

It's still happening. I don't know why. It was fine before adding the picnic blanket mod.
