I just don't know, my main house is in college, I send him to bed, time freezes between 5 am and 7 am or so. the game keeps going even on pause but the time freezes. If I exit to neighborhoods BE pops up, either way I get the same exception report.
"story_progression_action_sim_info_culling"
Exception in Sim Timeline: Exception running Element (KeyError: <sim '' 0xeb6154780970440>)
I have done the 50/50 thing hundreds of times, Removed Mods, etc. Everything. Updated all my mods. I had the game working fine and thought I had it traced to the Mod that seemed to cause the error but then, it happened again after it ran okay without Exceptions, I restart and the exception comes back.
I ran the game on a previous save file but it does the same thing. I have been dealing with this since the last update. When I think I have it fixed and it runs fine, and I don't change anything the error comes back.
