[ISSUE] Savegame Corruption

So I found a solution with out having to start a new game. 

Problem:

One sims icon was not showing his face and I could not click on him or move him. Then after restarting the game the whole family's icons disappeared, sometimes the house was invisible from the map. They were moving around though. Then I couldnt go into buy or build mode and could not see their needs or anything on that part of the screen in just this household. 

Solution:

• I evicted the household ( This is better than placing a copy in the library from the start because mine would freeze in processing) with the lot.
• Then when the house is in my clipboard I saved a copy to the library.  
• Go back to Game setup ( or whatever is at the top of the screen in the shape of a bar)
• Bulldozer the old lot completely leaving an empty lot. 
• Then you should be able to place the family with its house in the same location.

This worked 100% for me and I went through a lot of different things like resetting sims and moving them with cheat codes to delete them. 

Their jobs remain, their backpack inventory remains, THEIR RELATIONSHIPS WITH FRIENDS DO NOT. Their outfits remain. This was the best solution for me. I've been having alot of glitches lately and I did not even update or download anything. This specific glitch happened to me after installing Seasons and University. 

My previous glitch was my sim not going to work when the icon show us, it just vanished. I created a new career outfit and that solved that issue.
