Sims 4 thumbnail error
I've been having some issues with the Sims 4. My thumbnails are constantly glitching up, and it's quite a nuisance. This has happened in the previous games, too -- so I'm not sure if it's my computer, or what.
Here are my specs:
Windows XP Home Edition, SP3
Pentium Dual Core CPU E400 @ 2.70GHz
2.69GHz, 2.00 GB of RAM
ATI Radeon HD 4300/4500 Series
DirectX 9.0c

Best Answer
Go to My Documents -> Electronic Arts -> The Sims 4 (or wherever you store your games)
Delete the Cache directory and the localthumbcache file.
Launch Sims 4 again and the problem should be fixed. This happened to me a while ago too.
