Re: [CC and Milestones, error code 110-578ef827] Stuck On Loading Screen Sims 4
So I've tried everything for hours. Even followed the crintint Forum for troubleshooting this situation. I keep getting thrown into the World Manager selection screen when wanting to load my family. This only happened after installing the new update. I got an endless Last Exception file, which I've tried to figure out with ChatGPT together. I've updated every mod I can think of. I took them out, but then I get an infinite loading screen. The only thing I could do so far, is start a new vanilla game with renaming the Sims 4 folder into Sims 4_old.
So my own modded game, starting it up vanilla had just one Last Exception (shortened):
Server\developmental_milestones\developmental_milestone_tracker.py
-This is part of the vanilla game system that tracks infant/toddler/child/adult life milestones.
-No external creator is responsible for it — only Maxis/EA.
developmental_milestone_tracker.py", line 1114
KeyError: 'Object not found: 0x27a4b72'
-A Sim in your save is linked to a milestone object that got deleted or corrupted.
Could be from: -An infant/toddler aging up while holding a milestone link. -A household or Sim moved out with milestone data attached. -A rare EA-side bug where the milestone tracker references an invalid object ID
