Update
This bug was fixed in Patch 1.15.55
Problem
I get the following error message when I try to save my game
The Game failed to save. Error Code: 533:18217914019454249800

Cause
Unclear, but it could be a corrupt Sim or a Sim with no household (according to Deaderpool)
EA/Maxis is aware of the issue and working on a fix.
Solution
The error can be solved by moving the household out and back in.
- Go to the household manager
- Move your family out (sell your furniture) and place them on any free lot
- Move your family out again (sell your furniture) and place them on the original lot.
- Save your game
This is only a temporary workaround until EA/Maxis can fix the actual bug. It does let you save your progress. The error might come back later so save often.
