The "pethousehold" may be unnamed in your game, as it was in mine. If you list the households, it will come up as a file path ending with "UnnamedHousehold" or something similar. You can't destroy that, though. I used Twallan's MasterController to assign it a name and then destroyed it. The game is running smoothly now. Hope that makes sense.

Lo siento mucho. I have a mod that starts the game off paused automatically, so I didn't think of it. Silly oversight, but thanks nonetheless.

Linked is a save file that should crash around 3:28, if I remember correctly. It's always in the 0300 hour, but not always at the exact same time-- even if I reload the save file a bunch of times, the crash time will vary slightly. It's odd. As for what I'm doing that could contribute, it's hard to say-- I've left the game to run on its own free will for a while, without any outside commands by me, and it still happens.

Hey there. I'm also getting the weird CTD issue where the crashing always occurs between 2:30 AM and 3:50 AM, except for me it happens no matter which household I'm in. When I take Awesome out, the crashes stop. If I go back to an earlier save and replay the day, sometimes the crash won't happen. In this way, I'm moved forward in time slowly. I'd say the crashing happens about 75% of nights and literally only in that time frame.

edit: I'm all up to date and playing in Appaloosa Plains, FYI.
